关于Am335x_evm.dts中SD/MMC1pin脚的配置问题



专家好:

我想使能 Am335x_evm 板子的 SD/MMC1pin,请问该如何配置DTS,尤其是cd-gpios pin! 请问支持吗?

dts里默认只支持 SD/MMC0 的配置。

&mmc1 {
739        status = "okay";
740        vmmc-supply = <&vmmc_reg>;
741        bus-width = <4>;
742        pinctrl-names = "default";
743        pinctrl-0 = <&mmc1_pins>;
744        cd-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>;
745};

谢谢
