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 I2C-2.

Changed from v1
- rebase on top of linux-rockchip/for-next
- dt-binding: collect review tags
- SoC devicetree
- sort i2c and gpio in /aliases
- provide default pinctrl for controllers with only one set of
possible pins
- Radxa E20C devicetree: mark eeprom as read-only

Yao Zi (3):
dt-bindings: i2c: i2c-rk3x: Add compatible string for RK3528
arm64: dts: rockchip: Add I2C controllers for RK3528
arm64: dts: rockchip: Add onboard EEPROM for Radxa E20C
