Subject: siflower: sf21 device tree fix
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=cdf187f1e789b5f192440e3ecb89439242d36a44;p=openwrt%2Fstaging%2Fstintel.git

siflower: sf21 device tree fix

`i2c1` node was missing `resets`, so even when enabled, the driver would
not recognize it:
```
i2c_designware c101000.i2c: Unknown Synopsys component type: 0x00000000
```

With this fix, I2C pins on BPi-RV2 26-pin GPIO header are usable.
