Allwinner A10/A20 CAN controller Device Tree Bindings
-----------------------------------------------------
Required properties:
- compatible: "allwinner,sun4i-a10-can"
- reg: physical base address and size of the Allwinner A10/A20 CAN register map.
- interrupts: interrupt specifier for the sole interrupt.
- clock: phandle and clock specifier.
Example
-------
SoC common .dtsi file:
can0_pins_a: can0@0 {
allwinner,pins = "PH20","PH21";
allwinner,function = "can";
allwinner,drive = <0>;
allwinner,pull = <0>;
};
...
can0: can@01c2bc00 {
compatible = "allwinner,sun4i-a10-can";
reg = <0x01c2bc00 0x400>;
interrupts = <0 26 4>;
clocks = <&apb1_gates 4>;
status = "disabled";
};
Board specific .dts file:
can0: can@01c2bc00 {
pinctrl-names = "default";
pinctrl-0 = <&can0_pins_a>;
status = "okay";
};
