+Subject: [PATCH 1/7] pinctrl: armada-37xx: use correct OUTPUT_VAL register for
+ GPIOs > 31
+
+The controller has two consecutive OUTPUT_VAL registers and both
+holds output value for 32 GPIOs. Due to a missing adjustment, the
+current code always uses the first register while setting the
+output value whereas it should use the second one for GPIOs > 31.
+
+Add the missing armada_37xx_update_reg() call to adjust the register
+according to the 'offset' parameter of the function to fix the issue.

+Subject: [PATCH 2/7] pinctrl: armada-37xx: set GPIO output value before
+ setting direction
+
+Changing the direction before updating the output value in the
+OUTPUT_VAL register may result in a glitch on the output line
+if the previous value in the OUTPUT_VAL register is different
+from the one we want to set.
+
+In order to avoid that, update the output value before changing
+the direction.

+Subject: [PATCH v2] PCI: aardvark: Implement workaround for PCIe Completion Timeout
+Date: Tue, 2 Aug 2022 14:38:16 +0200
+X-Mailer: git-send-email 2.20.1
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+Precedence: bulk
+List-ID: <linux-pci.vger.kernel.org>
+
+Marvell Armada 3700 Functional Errata, Guidelines, and Restrictions
+document describes in erratum 3.12 PCIe Completion Timeout (Ref #: 251),
+that PCIe IP does not support a strong-ordered model for inbound posted vs.
+outbound completion.
+
+As a workaround for this erratum, DIS_ORD_CHK flag in Debug Mux Control
+register must be set. It disables the ordering check in the core between
+Completions and Posted requests received from the link.
+
+Marvell also suggests to do full memory barrier at the beginning of
+aardvark summary interrupt handler before calling interrupt handlers of
+endpoint drivers in order to minimize the risk for the race condition
+documented in the Erratum between the DMA done status reading and the
+completion of writing to the host memory.
+
+More details about this issue and suggested workarounds are in discussion:
+https://lore.kernel.org/linux-pci/BN9PR18MB425154FE5019DCAF2028A1D5DB8D9@BN9PR18MB4251.namprd18.prod.outlook.com/t/#u
+
+It was reported that enabling this workaround fixes instability issues and
+"Unhandled fault" errors when using 60 GHz WiFi 802.11ad card with Qualcomm
+QCA6335 chip under significant load which were caused by interrupt status
+stuck in the outbound CMPLT queue traced back to this erratum.
+
+This workaround fixes also kernel panic triggered after some minutes of
+usage 5 GHz WiFi 802.11ax card with Mediatek MT7915 chip:
+
+ Internal error: synchronous external abort: 96000210 [#1] SMP
+ Kernel panic - not syncing: Fatal exception in interrupt

+Subject: [PATCH 67/69] generic: Mangle bootloader's kernel arguments
+
+The command-line arguments provided by the boot loader will be
+appended to a new device tree property: bootloader-args.
+If there is a property "append-rootblock" in DT under /chosen
+and a root= option in bootloaders command line it will be parsed
+and added to DT bootargs with the form: <append-rootblock>XX.
+Only command line ATAG will be processed, the rest of the ATAGs
+sent by bootloader will be ignored.
+This is usefull in dual boot systems, to get the current root partition
+without afecting the rest of the system.
+
+
+This patch has been modified to be mvebu specific. The original patch
+did not pass the bootloader cmdline on if no append-rootblock stanza
+was found, resulting in blank cmdline and failure to boot.

+Subject: [PATCH] drivers: thermal: step_wise: add support for hysteresis
+
+Step wise governor increases the mitigation level when the temperature
+goes above a threshold and will decrease the mitigation when the
+temperature falls below the threshold. If it were a case, where the
+temperature hovers around a threshold, the mitigation will be applied
+and removed at every iteration. This reaction to the temperature is
+inefficient for performance.
+
+The use of hysteresis temperature could avoid this ping-pong of
+mitigation by relaxing the mitigation to happen only when the
+temperature goes below this lower hysteresis value.

+priorities, which creates a nasty fairness issue where traffic from one
+CPU can starve traffic from all other CPUs.
+
+Work around this issue by forcing all tx packets to go through one CPU,
+until this issue is fixed properly.

+Subject: mvpp2: support fetching mac address from nvmem
+
+The mvpp2 driver did not query nvmem for hardware mac addresses. This
+patch adds querying of mac addresses stored in nvmem cells as a further
+fallback option before assigning a random address.
+Purposely added separately to fwnode_get_mac_address() above to maintain
+existing behaviour with builtin adapter mac address still taking
+precedence.

+Subject: cpuidle: mvebu: indicate failure to enter deeper sleep states
+
+The cpuidle ->enter method expects the return value to be the sleep
+state we entered. Returning negative numbers or other codes is not
+permissible since coupled CPU idle was merged.
+
+At least some of the mvebu_v7_cpu_suspend() implementations return the
+value from cpu_suspend(), which returns zero if the CPU vectors back
+into the kernel via cpu_resume() (the success case), or the non-zero
+return value of the suspend actor, or one (failure cases).
+
+We do not want to be returning the failure case value back to CPU idle
+as that indicates that we successfully entered one of the deeper idle
+states. Always return zero instead, indicating that we slept for the
+shortest amount of time.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Turris Omnia's MCU provides various features that can be configured over
+I2C at address 0x2a. Add device-tree node.
+
+This does not carry a Fixes tag - we do not want this to get backported
+to stable kernels for the following reason: U-Boot since v2022.10
+inserts a phy-reset-gpio property into the WAN ethernet node pointing to
+the MCU node if it finds the MCU node with a cznic,turris-omnia-mcu
+compatible. Thus if this change got backported to a stable kernel, the
+WAN interface driver would defer probe indefinitely (since it would wait
+for the turris-omnia-mcu driver which would not be present).

+
+Add a new init_recovery() callback to struct 'i2c_bus_recovery_info'
+and modify the i2c_init_recovery() function to call that if specified
+instead of the generic i2c_gpio_init_recovery() function.
+
+This allows controller drivers to skip calling the generic code by
+implementing a dummy callback function, or alternatively to run a

+
+The I2C communication is completely broken on the Armada 3700 platform
+since commit 0b01392c18b9 ("i2c: pxa: move to generic GPIO recovery").
+
+For example, on the Methode uDPU board, probing of the two onboard
+temperature sensors fails ...
+
+ [ 7.271713] i2c i2c-0: using pinctrl states for GPIO recovery
+ [ 7.277503] i2c i2c-0: PXA I2C adapter
+ [ 7.282199] i2c i2c-1: using pinctrl states for GPIO recovery

+ [ 82.890614] lm75 1-0049: probe with driver lm75 failed with error -121
+
+... and accessing the plugged-in SFP modules also does not work:
+
+ [ 511.298537] sfp sfp-eth1: please wait, module slow to respond
+ [ 536.488530] sfp sfp-eth0: please wait, module slow to respond

+ [ 1090.888532] sfp sfp-eth0: failed to read EEPROM: -EREMOTEIO
+
+After a discussion [1], there was an attempt to fix the problem by
+reverting the offending change by commit 7b211c767121 ("Revert "i2c:
+pxa: move to generic GPIO recovery""), but that only helped to fix
+the issue in the 6.1.y stable tree. The reason behind the partial succes
+is that there was another change in commit 20cb3fce4d60 ("i2c: Set i2c
+pinctrl recovery info from it's device pinctrl") in the 6.3-rc1 cycle
+which broke things further.
+
+The cause of the problem is the same in case of both offending commits
+mentioned above. Namely, the I2C core code changes the pinctrl state to
+GPIO while running the recovery initialization code. Although the PXA
+specific initialization also does this, but the key difference is that
+it happens before the conrtoller is getting enabled in i2c_pxa_reset(),
+whereas in the case of the generic initialization it happens after that.
+
+To resolve the problem, provide an empty init_recovery() callback
+function thus preventing the I2C core to call the generic recovery
+initialization code.
+
+As the result this change restores the original behaviour, which in
+turn makes the I2C communication to work again as it can be seen from
+the following log:
+
+ [ 7.305277] i2c i2c-0: PXA I2C adapter
+ [ 7.310198] i2c i2c-1: PXA I2C adapter

+
+Under some circumstances I2C recovery fails on Armada 3700. At least
+on the Methode uDPU board, removing and replugging an SFP module fails
+often, like this:
+
+ [ 36.953127] sfp sfp-eth1: module removed
+ [ 38.468549] i2c i2c-1: i2c_pxa: timeout waiting for bus free
+ [ 38.486960] sfp sfp-eth1: module MENTECHOPTO POS22-LDCC-KR rev 1.0 sn MNC208U90009 dc 200828
+ [ 38.496867] mvneta d0040000.ethernet eth1: unsupported SFP module: no common interface modes
+ [ 38.521448] hwmon hwmon2: temp1_input not attached to any thermal zone
+ [ 39.249196] sfp sfp-eth1: module removed
+ ...
+ [ 292.568799] sfp sfp-eth1: please wait, module slow to respond
+ ...
+ [ 625.208814] sfp sfp-eth1: failed to read EEPROM: -EREMOTEIO
+
+Note that the 'unsupported SFP module' messages are not relevant. The
+module is used only for testing the I2C recovery funcionality, because
+the error can be triggered easily with this specific one.
+
+Enabling debug in the i2c-pxa driver reveals the following:
+
+ [ 82.034678] sfp sfp-eth1: module removed
+ [ 90.008654] i2c i2c-1: slave_0x50 error: timeout with active message
+ [ 90.015112] i2c i2c-1: msg_num: 2 msg_idx: 0 msg_ptr: 0
+ [ 90.020464] i2c i2c-1: IBMR: 00000003 IDBR: 000000a0 ICR: 000007e0 ISR: 00000802
+ [ 90.027906] i2c i2c-1: log:
+ [ 90.030787]
+
+This continues until the retries are exhausted ...
+
+ [ 110.192489] i2c i2c-1: slave_0x50 error: exhausted retries
+ [ 110.198012] i2c i2c-1: msg_num: 2 msg_idx: 0 msg_ptr: 0
+ [ 110.203323] i2c i2c-1: IBMR: 00000003 IDBR: 000000a0 ICR: 000007e0 ISR: 00000802
+ [ 110.210810] i2c i2c-1: log:
+ [ 110.213633]
+
+... then the whole sequence starts again ...
+
+ [ 115.368641] i2c i2c-1: slave_0x50 error: timeout with active message
+
+... while finally the SFP core gives up:
+
+ [ 671.975258] sfp sfp-eth1: failed to read EEPROM: -EREMOTEIO
+
+When we analyze the log, it can be seen that bit 1 and 11 is set in the
+ISR (Interface Status Register). Bit 1 indicates the ACK/NACK status, but
+the purpose of bit 11 is not documented in the driver code unfortunately.
+
+The 'Functional Specification' document of the Armada 3700 SoCs family
+however says that this bit indicates an 'Early Bus Busy' condition. The
+document also notes that whenever this bit is set, it is not possible to
+initiate a transaction on the I2C bus. The observed behaviour corresponds
+to this statement.
+
+Unfortunately, I2C recovery does not help as it never runs in this
+special case. Although the driver checks the busyness of the bus at
+several places, but since it does not consider the A3700 specific bit
+in these checks it can't determine the actual status of the bus correctly
+which results in the errors above.
+
+In order to fix the problem, add a new member to struct 'i2c_pxa' to
+store a controller specific bitmask containing the bits indicating the
+busy status, and use that in the code while checking the actual status
+of the bus. This ensures that the correct status can be determined on
+the Armada 3700 based devices without causing functional changes on
+devices based on other SoCs.
+
+With the change applied, the driver detects the busy condition, and runs
+the recovery process:
+
+ [ 742.617312] i2c i2c-1: state:i2c_pxa_wait_bus_not_busy:449: ISR=00000802, ICR=000007e0, IBMR=03
+ [ 742.626099] i2c i2c-1: i2c_pxa: timeout waiting for bus free
+ [ 742.631933] i2c i2c-1: recovery: resetting controller, ISR=0x00000802
+ [ 742.638421] i2c i2c-1: recovery: IBMR 0x00000003 ISR 0x00000000
+
+This clears the EBB bit in the ISR register, so it makes it possible to
+initiate transactions on the I2C bus again.
+
+After this patch, the SFP module used for testing can be removed and
+replugged numerous times without causing the error described at the
+beginning. Previously, the error happened after a few such attempts.
+
+The patch has been tested also with the following kernel versions:
+5.10.237, 5.15.182, 6.1.138, 6.6.90, 6.12.28, 6.14.6. It improves
+recoverabilty on all of them.
+
+Fixes: 7c9ec2c52518 ("i2c: pxa: implement generic i2c bus recovery")
+---
+Note: the patch is included in this series for completeness however
+it can be applied independently from the preceding patches. On kernels
+6.3+, it restores I2C functionality even in itself because it recovers
+the controller from the bad state described in the previous patch.

+Add a driver for the IEI WT61P803 PUZZLE microcontroller, used in some
+IEI Puzzle series devices. The microcontroller controls system power,
+temperature sensors, fans and LEDs.
+
+This driver implements the core functionality for device communication
+over the system serial (serdev bus). It handles MCU messages and the
+internal MCU properties. Some properties can be managed over sysfs.

+Subject: [PATCH 3/7] drivers: hwmon: Add the IEI WT61P803 PUZZLE HWMON driver
+
+Add the IEI WT61P803 PUZZLE HWMON driver, that handles the fan speed
+control via PWM, reading fan speed and reading on-board temperature
+sensors.
+
+The driver registers a HWMON device and a simple thermal cooling device to
+enable in-kernel fan management.
+
+This driver depends on the IEI WT61P803 PUZZLE MFD driver.

+Subject: [PATCH 4/7] drivers: leds: Add the IEI WT61P803 PUZZLE LED driver
+
+Add support for the IEI WT61P803 PUZZLE LED driver.
+Currently only the front panel power LED is supported,
+since it is the only LED on this board wired through the
+MCU.
+
+The LED is wired directly to the on-board MCU controller
+and is toggled using an MCU command.
+
+Support for more LEDs is going to be added in case more
+boards implement this microcontroller, as LEDs use many
+different GPIOs.
+
+This driver depends on the IEI WT61P803 PUZZLE MFD driver.

-Subject: [PATCH 1/7] pinctrl: armada-37xx: use correct OUTPUT_VAL register for
- GPIOs > 31
-
-The controller has two consecutive OUTPUT_VAL registers and both
-holds output value for 32 GPIOs. Due to a missing adjustment, the
-current code always uses the first register while setting the
-output value whereas it should use the second one for GPIOs > 31.
-
-Add the missing armada_37xx_update_reg() call to adjust the register
-according to the 'offset' parameter of the function to fix the issue.

-Subject: [PATCH v2] PCI: aardvark: Implement workaround for PCIe Completion Timeout
-Date: Tue, 2 Aug 2022 14:38:16 +0200
-X-Mailer: git-send-email 2.20.1
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-Precedence: bulk
-List-ID: <linux-pci.vger.kernel.org>
-
-Marvell Armada 3700 Functional Errata, Guidelines, and Restrictions
-document describes in erratum 3.12 PCIe Completion Timeout (Ref #: 251),
-that PCIe IP does not support a strong-ordered model for inbound posted vs.
-outbound completion.
-
-As a workaround for this erratum, DIS_ORD_CHK flag in Debug Mux Control
-register must be set. It disables the ordering check in the core between
-Completions and Posted requests received from the link.
-
-Marvell also suggests to do full memory barrier at the beginning of
-aardvark summary interrupt handler before calling interrupt handlers of
-endpoint drivers in order to minimize the risk for the race condition
-documented in the Erratum between the DMA done status reading and the
-completion of writing to the host memory.
-
-More details about this issue and suggested workarounds are in discussion:
-https://lore.kernel.org/linux-pci/BN9PR18MB425154FE5019DCAF2028A1D5DB8D9@BN9PR18MB4251.namprd18.prod.outlook.com/t/#u
-
-It was reported that enabling this workaround fixes instability issues and
-"Unhandled fault" errors when using 60 GHz WiFi 802.11ad card with Qualcomm
-QCA6335 chip under significant load which were caused by interrupt status
-stuck in the outbound CMPLT queue traced back to this erratum.
-
-This workaround fixes also kernel panic triggered after some minutes of
-usage 5 GHz WiFi 802.11ax card with Mediatek MT7915 chip:
-
- Internal error: synchronous external abort: 96000210 [#1] SMP
- Kernel panic - not syncing: Fatal exception in interrupt
-
-Fixes: 8c39d710363c ("PCI: aardvark: Add Aardvark PCI host controller driver")

-Subject: [PATCH 67/69] generic: Mangle bootloader's kernel arguments
-
-The command-line arguments provided by the boot loader will be
-appended to a new device tree property: bootloader-args.
-If there is a property "append-rootblock" in DT under /chosen
-and a root= option in bootloaders command line it will be parsed
-and added to DT bootargs with the form: <append-rootblock>XX.
-Only command line ATAG will be processed, the rest of the ATAGs
-sent by bootloader will be ignored.
-This is usefull in dual boot systems, to get the current root partition
-without afecting the rest of the system.
-
-
-This patch has been modified to be mvebu specific. The original patch
-did not pass the bootloader cmdline on if no append-rootblock stanza
-was found, resulting in blank cmdline and failure to boot.

-Subject: [PATCH] drivers: thermal: step_wise: add support for hysteresis
-
-Step wise governor increases the mitigation level when the temperature
-goes above a threshold and will decrease the mitigation when the
-temperature falls below the threshold. If it were a case, where the
-temperature hovers around a threshold, the mitigation will be applied
-and removed at every iteration. This reaction to the temperature is
-inefficient for performance.
-
-The use of hysteresis temperature could avoid this ping-pong of
-mitigation by relaxing the mitigation to happen only when the
-temperature goes below this lower hysteresis value.
-
-[forward-ported for Linux 6.6, as stop-gap downstream solution]

-Subject: cpuidle: mvebu: indicate failure to enter deeper sleep states
-
-The cpuidle ->enter method expects the return value to be the sleep
-state we entered. Returning negative numbers or other codes is not
-permissible since coupled CPU idle was merged.
-
-At least some of the mvebu_v7_cpu_suspend() implementations return the
-value from cpu_suspend(), which returns zero if the CPU vectors back
-into the kernel via cpu_resume() (the success case), or the non-zero
-return value of the suspend actor, or one (failure cases).
-
-We do not want to be returning the failure case value back to CPU idle
-as that indicates that we successfully entered one of the deeper idle
-states. Always return zero instead, indicating that we slept for the
-shortest amount of time.

- poweroff and wakeup
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add support for true board poweroff (MCU can disable all unnecessary
-voltage regulators) and wakeup at a specified time, implemented via a
-RTC driver so that the rtcwake utility can be used to configure it.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Turris Omnia's MCU provides various features that can be configured over
-I2C at address 0x2a. Add device-tree node.
-
-This does not carry a Fixes tag - we do not want this to get backported
-to stable kernels for the following reason: U-Boot since v2022.10
-inserts a phy-reset-gpio property into the WAN ethernet node pointing to
-the MCU node if it finds the MCU node with a cznic,turris-omnia-mcu
-compatible. Thus if this change got backported to a stable kernel, the
-WAN interface driver would defer probe indefinitely (since it would wait
-for the turris-omnia-mcu driver which would not be present).

-The newly added driver causes a Kconfig warning:
-
-WARNING: unmet direct dependencies detected for RTC_CLASS
- Depends on [n]: !S390 [=y]
- Selected by [m]:

-The problem here is that it selects entire subsystems, which normal
-device drivers should not do. Changes all of these to 'depends on'
-instead.

-Add a new init_recovery() callback to struct 'i2c_bus_recovery_info'
-and modify the i2c_init_recovery() function to call that if specified
-instead of the generic i2c_gpio_init_recovery() function.
-
-This allows controller drivers to skip calling the generic code by
-implementing a dummy callback function, or alternatively to run a
-fine tuned custom implementation.
-
-This is needed for the 'i2c-pxa' driver in order to be able to fix
-a long standing bug for which the fix will be implemented in a
-followup patch.

-
-The I2C communication is completely broken on the Armada 3700 platform
-since commit 0b01392c18b9 ("i2c: pxa: move to generic GPIO recovery").
-
-For example, on the Methode uDPU board, probing of the two onboard
-temperature sensors fails ...
-
- [ 7.271713] i2c i2c-0: using pinctrl states for GPIO recovery
- [ 7.277503] i2c i2c-0: PXA I2C adapter
- [ 7.282199] i2c i2c-1: using pinctrl states for GPIO recovery

- [ 7.292947] sfp sfp-eth1: Host maximum power 3.0W

- [ 32.496833] lm75 1-0049: supply vs not found, using dummy regulator
- [ 82.890614] lm75 1-0049: probe with driver lm75 failed with error -121
-
-... and accessing the plugged-in SFP modules also does not work:
-
- [ 511.298537] sfp sfp-eth1: please wait, module slow to respond
- [ 536.488530] sfp sfp-eth0: please wait, module slow to respond

- [ 1090.888532] sfp sfp-eth0: failed to read EEPROM: -EREMOTEIO
-
-After a discussion [1], there was an attempt to fix the problem by
-reverting the offending change by commit 7b211c767121 ("Revert "i2c:
-pxa: move to generic GPIO recovery""), but that only helped to fix
-the issue in the 6.1.y stable tree. The reason behind the partial succes
-is that there was another change in commit 20cb3fce4d60 ("i2c: Set i2c
-pinctrl recovery info from it's device pinctrl") in the 6.3-rc1 cycle
-which broke things further.
-
-The cause of the problem is the same in case of both offending commits
-mentioned above. Namely, the I2C core code changes the pinctrl state to
-GPIO while running the recovery initialization code. Although the PXA
-specific initialization also does this, but the key difference is that
-it happens before the conrtoller is getting enabled in i2c_pxa_reset(),
-whereas in the case of the generic initialization it happens after that.
-
-To resolve the problem, provide an empty init_recovery() callback
-function thus preventing the I2C core to call the generic recovery
-initialization code.
-
-As the result this change restores the original behaviour, which in
-turn makes the I2C communication to work again as it can be seen from
-the following log:
-
- [ 7.305277] i2c i2c-0: PXA I2C adapter

-Under some circumstances I2C recovery fails on Armada 3700. At least
-on the Methode uDPU board, removing and replugging an SFP module fails
-often, like this:
-
- [ 36.953127] sfp sfp-eth1: module removed
- [ 38.468549] i2c i2c-1: i2c_pxa: timeout waiting for bus free
- [ 38.486960] sfp sfp-eth1: module MENTECHOPTO POS22-LDCC-KR rev 1.0 sn MNC208U90009 dc 200828
- [ 38.496867] mvneta d0040000.ethernet eth1: unsupported SFP module: no common interface modes
- [ 38.521448] hwmon hwmon2: temp1_input not attached to any thermal zone
- [ 39.249196] sfp sfp-eth1: module removed
- ...
- [ 292.568799] sfp sfp-eth1: please wait, module slow to respond
- ...
- [ 625.208814] sfp sfp-eth1: failed to read EEPROM: -EREMOTEIO
-
-Note that the 'unsupported SFP module' messages are not relevant. The
-module is used only for testing the I2C recovery funcionality, because
-the error can be triggered easily with this specific one.
-
-Enabling debug in the i2c-pxa driver reveals the following:
-
- [ 82.034678] sfp sfp-eth1: module removed
- [ 90.008654] i2c i2c-1: slave_0x50 error: timeout with active message
- [ 90.015112] i2c i2c-1: msg_num: 2 msg_idx: 0 msg_ptr: 0
- [ 90.020464] i2c i2c-1: IBMR: 00000003 IDBR: 000000a0 ICR: 000007e0 ISR: 00000802
- [ 90.027906] i2c i2c-1: log:
- [ 90.030787]
-
-This continues until the retries are exhausted ...
-
- [ 110.192489] i2c i2c-1: slave_0x50 error: exhausted retries
- [ 110.198012] i2c i2c-1: msg_num: 2 msg_idx: 0 msg_ptr: 0
- [ 110.203323] i2c i2c-1: IBMR: 00000003 IDBR: 000000a0 ICR: 000007e0 ISR: 00000802
- [ 110.210810] i2c i2c-1: log:
- [ 110.213633]
-
-... then the whole sequence starts again ...
-
- [ 115.368641] i2c i2c-1: slave_0x50 error: timeout with active message
-
-... while finally the SFP core gives up:
-
- [ 671.975258] sfp sfp-eth1: failed to read EEPROM: -EREMOTEIO
-
-When we analyze the log, it can be seen that bit 1 and 11 is set in the
-ISR (Interface Status Register). Bit 1 indicates the ACK/NACK status, but
-the purpose of bit 11 is not documented in the driver code unfortunately.
-
-The 'Functional Specification' document of the Armada 3700 SoCs family
-however says that this bit indicates an 'Early Bus Busy' condition. The
-document also notes that whenever this bit is set, it is not possible to
-initiate a transaction on the I2C bus. The observed behaviour corresponds
-to this statement.
-
-Unfortunately, I2C recovery does not help as it never runs in this
-special case. Although the driver checks the busyness of the bus at
-several places, but since it does not consider the A3700 specific bit
-in these checks it can't determine the actual status of the bus correctly
-which results in the errors above.
-
-In order to fix the problem, add a new member to struct 'i2c_pxa' to
-store a controller specific bitmask containing the bits indicating the
-busy status, and use that in the code while checking the actual status
-of the bus. This ensures that the correct status can be determined on
-the Armada 3700 based devices without causing functional changes on
-devices based on other SoCs.
-
-With the change applied, the driver detects the busy condition, and runs
-the recovery process:
-
- [ 742.617312] i2c i2c-1: state:i2c_pxa_wait_bus_not_busy:449: ISR=00000802, ICR=000007e0, IBMR=03
- [ 742.626099] i2c i2c-1: i2c_pxa: timeout waiting for bus free
- [ 742.631933] i2c i2c-1: recovery: resetting controller, ISR=0x00000802
- [ 742.638421] i2c i2c-1: recovery: IBMR 0x00000003 ISR 0x00000000
-
-This clears the EBB bit in the ISR register, so it makes it possible to
-initiate transactions on the I2C bus again.
-
-After this patch, the SFP module used for testing can be removed and
-replugged numerous times without causing the error described at the
-beginning. Previously, the error happened after a few such attempts.
-
-The patch has been tested also with the following kernel versions:
-5.10.237, 5.15.182, 6.1.138, 6.6.90, 6.12.28, 6.14.6. It improves
-recoverabilty on all of them.
-
-Fixes: 7c9ec2c52518 ("i2c: pxa: implement generic i2c bus recovery")
----
-Note: the patch is included in this series for completeness however
-it can be applied independently from the preceding patches. On kernels
-6.3+, it restores I2C functionality even in itself because it recovers
-the controller from the bad state described in the previous patch.

-
-Add a driver for the IEI WT61P803 PUZZLE microcontroller, used in some
-IEI Puzzle series devices. The microcontroller controls system power,
-temperature sensors, fans and LEDs.
-
-This driver implements the core functionality for device communication
-over the system serial (serdev bus). It handles MCU messages and the
-internal MCU properties. Some properties can be managed over sysfs.

-Subject: [PATCH 3/7] drivers: hwmon: Add the IEI WT61P803 PUZZLE HWMON driver
-
-Add the IEI WT61P803 PUZZLE HWMON driver, that handles the fan speed
-control via PWM, reading fan speed and reading on-board temperature
-sensors.
-
-The driver registers a HWMON device and a simple thermal cooling device to
-enable in-kernel fan management.
-
-This driver depends on the IEI WT61P803 PUZZLE MFD driver.

-Subject: [PATCH 4/7] drivers: leds: Add the IEI WT61P803 PUZZLE LED driver
-
-Add support for the IEI WT61P803 PUZZLE LED driver.
-Currently only the front panel power LED is supported,
-since it is the only LED on this board wired through the
-MCU.
-
-The LED is wired directly to the on-board MCU controller
-and is toggled using an MCU command.
-
-Support for more LEDs is going to be added in case more
-boards implement this microcontroller, as LEDs use many
-different GPIOs.
-
-This driver depends on the IEI WT61P803 PUZZLE MFD driver.
