我的2个spi配置为
&spi1 {
    status = "okay";
    max-freq = <48000000>;
    pinctrl-names = "default";
    pinctrl-0 = <&spi1_clk &spi1_tx &spi1_rx &spi1_cs0>;
    spidev1@10 {
        compatible = "rockchip,spidev1";
        reg = <0>;   //chip select  0:cs0  1:cs1
        spi-max-frequency = <10000000>;   //spi output clock
    };

};

&spi3 {
    status = "okay";
    max-freq = <48000000>;
    pinctrl-names = "default";
    pinctrl-0 = <&spi3_clk &spi3_tx &spi3_rx &spi3_cs0>;
    spidev3@30 {
        compatible = "rockchip,spidev3";
        reg = <0>;   //chip select  0:cs0  1:cs1
        //id = <0>;
        spi-max-frequency = <10000000>;   //spi output clock
        //spi-cpha;      not support
        //spi-cpol;     //if the property is here it is 1:clk is high, else 0:clk is low  when idle
    };

};




&pinctrl {
    spi1 {
        spi1_clk: spi1-clk {
            rockchip,pins = <4 19 RK_FUNC_2 &pcfg_pull_up>;
        };
        spi1_cs0: spi1-cs0 {
            rockchip,pins = <4 18 RK_FUNC_2 &pcfg_pull_up>;
        };
        spi1_rx: spi1-rx {
            rockchip,pins = <4 17 RK_FUNC_2 &pcfg_pull_up>;
        };
        spi1_tx: spi1-tx {
            rockchip,pins = <4 1 RK_FUNC_2 &pcfg_pull_up>;
        };
    };

    spi3 {
        spi3_clk: spi3-clk {
            rockchip,pins = <5 19 RK_FUNC_1 &pcfg_pull_up>;
        };
        spi3_cs0: spi3-cs0 {
            rockchip,pins = <5 22 RK_FUNC_1 &pcfg_pull_up>;
        };
        spi3_rx: spi3-rx {
            rockchip,pins = <5 21 RK_FUNC_1 &pcfg_pull_up>;
        };
        spi3_tx: spi3-tx {
            rockchip,pins = <5 18 RK_FUNC_1 &pcfg_pull_up>;
        };
    };



}

spi 的 pinctrl 是已经设置好的，在rk3568-pinctrl.dtsi里面，其他dts只能引用选择m0组或m1组
不要这样重新分配，参考rk3568-firefly-port.dtsi里面进行设置

请问下spi1 与spi3的子系统都不用写了，都是可以直接用的吗？ 我的项目时用可rk3566核心板，我们自己的底板用了spi1与spi3.一个接了flash一个接了芯片。 请问我依然使用你上面说的配置就行了吗

参考rk3568-firefly-port.dtsi你只需要设置pinctrl组，频率，dev-port，然后添加你的设备节点就行了
SDK里doc文件夹下也有文档
