参考ROCKCHIP说明书，编制如下配置文件，编译后系统仅显示SPI1.0，没有出现SPI1.1，请问哪里出现问题？
&spi1 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&spi1m0_pins>;
#address-cells = <1>;
#size-cells = <0>;
spidev0@0 {
compatible = "rockchip,spidev";
spi-max-frequency = <50000000>;
id = <0>;
reg = <0>;
};
spidev1@1 {
compatible = "rockchip,spidev";
spi-max-frequency = <50000000>;
id = <1>;
reg = <1>;
};

};
&pinctrl {
spi1 {
/omit-if-no-ref/
spi1m0_pins: spi1m0-pins {
rockchip,pins =
/* spi1_cs0_m0 */
<4 RK_PA5 2 &pcfg_pull_none>,
/* spi1_clk_m0 */
<4 RK_PA7 2 &pcfg_pull_none>,
/* spi1_miso_m0 */
<4 RK_PA0 2 &pcfg_pull_none>,
/* spi1_mosi_m0 */
<4 RK_PA1 2 &pcfg_pull_none>;
};
};
};

您好，需要让spi同时管理两个设备需要设置两个片选引脚，参考

Code: Select all

 &spi0 {
        pinctrl-0 = <&spi0m0_clk &spi0m0_miso &spi0m0_mosi &spi0m0_cs0 &spi0m0_cs1>;
        #address-cells = <1>;
        #size-cells = <0>;
        num-cs = <2>;

        spidev@0 {
                compatible = "rockchip,spidev";
                spi-max-frequency = <50000000>;
                reg = <0>;
        };
        spidev@1 {
                compatible = "rockchip,spidev";
                spi-max-frequency = <50000000>;
                reg = <1>;
        };
};

Luckfox Pico Max 的SPI1引脚没有引出
