Based on patches for Gray Hawk in the BSP by Hai Pham. Signed-off-by: Geert Uytterhoeven Reviewed-by: Wolfram Sang --- The Gray Hawk Single documentation does not mention the purpose of the I2C EEPROMs, but the schematics label the last two as "Board ID". The labels match the corresponding EEPROMs on the White Hawk CPU and BreakOut board stack, from which the Gray Hawk Single board is derived. --- .../dts/renesas/r8a779h0-gray-hawk-single.dts | 41 +++++++++++++++++++ 1 file changed, 41 insertions(+) diff --git a/arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts b/arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts index 1c84fe7171d3fd85..1bee27b2284d2eee 100644 --- a/arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts +++ b/arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts @@ -50,6 +50,42 @@ &hscif0 { status = "okay"; }; +&i2c0 { + pinctrl-0 = <&i2c0_pins>; + pinctrl-names = "default"; + + status = "okay"; + clock-frequency = <400000>; + + eeprom@50 { + compatible = "rohm,br24g01", "atmel,24c01"; + label = "cpu-board"; + reg = <0x50>; + pagesize = <8>; + }; + + eeprom@51 { + compatible = "rohm,br24g01", "atmel,24c01"; + label = "breakout-board"; + reg = <0x51>; + pagesize = <8>; + }; + + eeprom@52 { + compatible = "rohm,br24g01", "atmel,24c01"; + label = "csi-dsi-sub-board-id"; + reg = <0x52>; + pagesize = <8>; + }; + + eeprom@53 { + compatible = "rohm,br24g01", "atmel,24c01"; + label = "ethernet-sub-board-id"; + reg = <0x53>; + pagesize = <8>; + }; +}; + &pfc { pinctrl-0 = <&scif_clk_pins>; pinctrl-names = "default"; @@ -59,6 +95,11 @@ hscif0_pins: hscif0 { function = "hscif0"; }; + i2c0_pins: i2c0 { + groups = "i2c0"; + function = "i2c0"; + }; + scif_clk_pins: scif_clk { groups = "scif_clk"; function = "scif_clk";
