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 .../devicetree/bindings/i2c/i2c-rk3x.yaml | 1 + .../boot/dts/rockchip/rk3528-radxa-e20c.dts | 14 +++ arch/arm64/boot/dts/rockchip/rk3528.dtsi | 110 ++++++++++++++++++ 3 files changed, 125 insertions(+)
