+Subject: [PATCH] arm64: dts: rockchip: move rk3528 i2c+uart aliases to board
+ files
+
+Even though they will be the same for all boards, i2c and uart aliases
+are supposed to live in the individual board files, to not create
+aliases for disabled nodes.
+
+So move the newly added aliases for rk3528 over to the Radxa E20C board,
+which is the only rk3528 board right now.
+
+Fixes: d3a05f490d04 ("arm64: dts: rockchip: Add I2C controllers for RK3528")

+eMMC HS200 mode (1.8V I/O) is supported by the MMC host controller on

+
+Radxa E20C provides one of its GbE ports through RTL8111H connected to
+SoC's PCIe controller. Let's enable the controller and the PHY used by
+it to allow usage of the port.
