Add device nodes for the GPIO controllers on the Renesas R-Car M3-W+ (r8a77961) SoC. Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> --- v2: - No changes. Test procedure (with "arm64: dts: renesas: r8a77961: Add RAVB node"): 1. "ifconfig eth0 1.2.3.4", 2. "watch grep e6052000.gpio /proc/interrupts", 3. See interrupt count increase when Ethernet link goes up. --- arch/arm64/boot/dts/renesas/r8a77961.dtsi | 85 +++++++++++++++++++++-- 1 file changed, 80 insertions(+), 5 deletions(-) diff --git a/arch/arm64/boot/dts/renesas/r8a77961.dtsi b/arch/arm64/boot/dts/renesas/r8a77961.dtsi index ea2c6445977f3d99..10e768ce2bc70e0c 100644 --- a/arch/arm64/boot/dts/renesas/r8a77961.dtsi +++ b/arch/arm64/boot/dts/renesas/r8a77961.dtsi @@ -328,49 +328,124 @@ status = "disabled"; }; + gpio0: gpio@e6050000 { + compatible = "renesas,gpio-r8a77961", + "renesas,rcar-gen3-gpio"; + reg = <0 0xe6050000 0 0x50>; + interrupts = <GIC_SPI 4 IRQ_TYPE_LEVEL_HIGH>; + #gpio-cells = <2>; + gpio-controller; + gpio-ranges = <&pfc 0 0 16>; + #interrupt-cells = <2>; + interrupt-controller; + clocks = <&cpg CPG_MOD 912>; + power-domains = <&sysc R8A77961_PD_ALWAYS_ON>; + resets = <&cpg 912>; + }; + + gpio1: gpio@e6051000 { + compatible = "renesas,gpio-r8a77961", + "renesas,rcar-gen3-gpio"; + reg = <0 0xe6051000 0 0x50>; + interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>; + #gpio-cells = <2>; + gpio-controller; + gpio-ranges = <&pfc 0 32 29>; + #interrupt-cells = <2>; + interrupt-controller; + clocks = <&cpg CPG_MOD 911>; + power-domains = <&sysc R8A77961_PD_ALWAYS_ON>; + resets = <&cpg 911>; + }; + gpio2: gpio@e6052000 { + compatible = "renesas,gpio-r8a77961", + "renesas,rcar-gen3-gpio"; reg = <0 0xe6052000 0 0x50>; + interrupts = <GIC_SPI 6 IRQ_TYPE_LEVEL_HIGH>; #gpio-cells = <2>; gpio-controller; + gpio-ranges = <&pfc 0 64 15>; #interrupt-cells = <2>; interrupt-controller; - /* placeholder */ + clocks = <&cpg CPG_MOD 910>; + power-domains = <&sysc R8A77961_PD_ALWAYS_ON>; + resets = <&cpg 910>; }; gpio3: gpio@e6053000 { + compatible = "renesas,gpio-r8a77961", + "renesas,rcar-gen3-gpio"; reg = <0 0xe6053000 0 0x50>; + interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>; #gpio-cells = <2>; gpio-controller; + gpio-ranges = <&pfc 0 96 16>; #interrupt-cells = <2>; interrupt-controller; - /* placeholder */ + clocks = <&cpg CPG_MOD 909>; + power-domains = <&sysc R8A77961_PD_ALWAYS_ON>; + resets = <&cpg 909>; }; gpio4: gpio@e6054000 { + compatible = "renesas,gpio-r8a77961", + "renesas,rcar-gen3-gpio"; reg = <0 0xe6054000 0 0x50>; + interrupts = <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>; #gpio-cells = <2>; gpio-controller; + gpio-ranges = <&pfc 0 128 18>; #interrupt-cells = <2>; interrupt-controller; - /* placeholder */ + clocks = <&cpg CPG_MOD 908>; + power-domains = <&sysc R8A77961_PD_ALWAYS_ON>; + resets = <&cpg 908>; }; gpio5: gpio@e6055000 { + compatible = "renesas,gpio-r8a77961", + "renesas,rcar-gen3-gpio"; reg = <0 0xe6055000 0 0x50>; + interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>; #gpio-cells = <2>; gpio-controller; + gpio-ranges = <&pfc 0 160 26>; #interrupt-cells = <2>; interrupt-controller; - /* placeholder */ + clocks = <&cpg CPG_MOD 907>; + power-domains = <&sysc R8A77961_PD_ALWAYS_ON>; + resets = <&cpg 907>; }; gpio6: gpio@e6055400 { + compatible = "renesas,gpio-r8a77961", + "renesas,rcar-gen3-gpio"; reg = <0 0xe6055400 0 0x50>; + interrupts = <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>; #gpio-cells = <2>; gpio-controller; + gpio-ranges = <&pfc 0 192 32>; #interrupt-cells = <2>; interrupt-controller; - /* placeholder */ + clocks = <&cpg CPG_MOD 906>; + power-domains = <&sysc R8A77961_PD_ALWAYS_ON>; + resets = <&cpg 906>; + }; + + gpio7: gpio@e6055800 { + compatible = "renesas,gpio-r8a77961", + "renesas,rcar-gen3-gpio"; + reg = <0 0xe6055800 0 0x50>; + interrupts = <GIC_SPI 11 IRQ_TYPE_LEVEL_HIGH>; + #gpio-cells = <2>; + gpio-controller; + gpio-ranges = <&pfc 0 224 4>; + #interrupt-cells = <2>; + interrupt-controller; + clocks = <&cpg CPG_MOD 905>; + power-domains = <&sysc R8A77961_PD_ALWAYS_ON>; + resets = <&cpg 905>; }; pfc: pin-controller@e6060000 { -- 2.17.1
