The absence of automatic transmission registers leads us to declare the r8a77990 IIC controller as incompatible. v2.1 * Reduced register range to reflect documentation Signed-off-by: Takeshi Kihara Signed-off-by: Yoshihiro Kaneko Signed-off-by: Simon Horman Reviewed-by: Geert Uytterhoeven Signed-off-by: Simon Horman --- diff --git a/arch/arm64/boot/dts/renesas/r8a77990.dtsi b/arch/arm64/boot/dts/renesas/r8a77990.dtsi index b0398e05e8ed..3b334be843f4 100644 --- a/arch/arm64/boot/dts/renesas/r8a77990.dtsi +++ b/arch/arm64/boot/dts/renesas/r8a77990.dtsi @@ -357,6 +357,20 @@ reg = <0 0xe6060000 0 0x508>; }; + i2c_dvfs: i2c@e60b0000 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "renesas,iic-r8a77990"; + reg = <0 0xe60b0000 0 0x15>; + interrupts = ; + clocks = <&cpg CPG_MOD 926>; + power-domains = <&sysc R8A77990_PD_ALWAYS_ON>; + resets = <&cpg 926>; + dmas = <&dmac0 0x11>, <&dmac0 0x10>; + dma-names = "tx", "rx"; + status = "disabled"; + }; + cpg: clock-controller@e6150000 { compatible = "renesas,r8a77990-cpg-mssr"; reg = <0 0xe6150000 0 0x1000>;
