|
-----------------------------------------------------
|
|
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@1c2bc00 {
|
compatible = "allwinner,sun4i-a10-can";
|
reg = <0x01c2bc00 0x400>;
|
interrupts = <0 26 4>;
|
clocks = <&apb1_gates 4>;
|
status = "disabled";
|
};
|
|
Board specific .dts file:
|
|
can0: can@1c2bc00 {
|
pinctrl-names = "default";
|
pinctrl-0 = <&can0_pins_a>;
|
status = "okay";
|
};
