The A20 SoC has an on-board CAN controller. This patch adds the device node and the corresponding pinctrl settings for pins PH20 and PH21. The CAN controller is inherited from the A10 SoC and uses the same driver. This patch is adapted from the description in Documentation/devicetree/bindings/net/can/sun4i_can.txt Signed-off-by: Patrick Menschel <menschel.p@xxxxxxxxx> --- arch/arm/boot/dts/sun7i-a20.dtsi | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/arch/arm/boot/dts/sun7i-a20.dtsi b/arch/arm/boot/dts/sun7i-a20.dtsi index 2db97fc..25af586 100644 --- a/arch/arm/boot/dts/sun7i-a20.dtsi +++ b/arch/arm/boot/dts/sun7i-a20.dtsi @@ -1096,6 +1096,11 @@ #interrupt-cells = <3>; #gpio-cells = <3>; + can0_pins_a: can0@0 { + pins = "PH20","PH21"; + function = "can"; + }; + clk_out_a_pins_a: clk_out_a@0 { pins = "PI12"; function = "clk_out_a"; @@ -1582,6 +1587,14 @@ #size-cells = <0>; }; + can0: can@01c2bc00 { + compatible = "allwinner,sun4i-a10-can"; + reg = <0x01c2bc00 0x400>; + interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&apb1_gates 4>; + status = "disabled"; + }; + i2c4: i2c@01c2c000 { compatible = "allwinner,sun7i-a20-i2c", "allwinner,sun4i-a10-i2c"; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
