我需要使用所有SPI外设 ,同时每个SPI的 两个片选都启用 我应该怎么配置设备树 #9
Description
&spi0 {
status = "okay";
pinctrl-names = "default";
spi-max-frequency = <30000000>;
pinctrl-0 = <&pinctrl_spi0>;
#address-cells = <1>;
#size-cells = <0>;
spidev0_0: spidev@0 {
compatible = "my_spidev";
reg = <0>;
spi-max-frequency = <12000000>;
};
spidev0_1: spidev@1 {
compatible = "my_spidev";
reg = <1>;
spi-max-frequency = <12000000>;
};
};
这个配置对吗
