RK3528 integrates eight I2C controllers which are compatible with the
RK3399 variant of i2c-rk3x. This series documents the controllers in
dt-bindings, describe them in SoC devicetree and enable the onboard
EEPROM of Radxa E20C which is connected to the second I2C controller.

This series is based on linux-rockchip/for-next and may depend on the
v3 of SD/SDIO series for a clean apply[1].
