  2. DTS 配置
    CAN 模块基本配置
    can0: can@19230000 {
    compatible = "artc,artc-can";
    reg = <0x0 0x19230000 0x0 0x400>;
    interrupts-extended = <&plic0 88 IRQ_TYPE_LEVEL_HIGH>;
    clocks = <&cmu CLK_CAN0>;
    resets = <&rst RESET_CAN0>;
};

can1: can@19231000 {
    compatible = "artc,artc-can";
    reg = <0x0 0x19231000 0x0 0x400>;
    interrupts-extended = <&plic0 89 IRQ_TYPE_LEVEL_HIGH>;
    clocks = <&cmu CLK_CAN1>;
    resets = <&rst RESET_CAN1>;
};
    xxx/board.dts 配置
    &can0 {
    pinctrl-names = "default";
    pinctrl-0 = <&can0_pins>;
    status = "okay";
};

&can1 {
    pinctrl-names = "default";
    pinctrl-0 = <&can1_pins>;
    status = "okay";
