Card Detect not working in Kernel 4.1.15

Hello,

I'm testing the new kernel and I can't get cd-gpios working, the same device tree works well with kernel 3.14.52

This is the relevant fragment of the DT:

Declared inside the pinhog:

+&usdhc3 {

+ pinctrl-names = "default", "state_100mhz", "state_200mhz";

+ pinctrl-0 = <&pinctrl_usdhc3>;

+ pinctrl-1 = <&pinctrl_usdhc3_100mhz>;

+ pinctrl-2 = <&pinctrl_usdhc3_200mhz>;

+ cd-gpios = <&gpio3 20 GPIO_ACTIVE_LOW>;

+ vmmc-supply = <&reg_sd3_vmmc>;

+ vqmmc-1-8-v = <1>;

+ bus-width = <4>;

+ keep-power-in-suspend;

+ enable-sdio-wakeup;

+ status = "okay";

+};

+&usdhc4 {

+ pinctrl-names = "default", "state_100mhz", "state_200mhz";

+ pinctrl-0 = <&pinctrl_usdhc4>;

+ pinctrl-1 = <&pinctrl_usdhc4_100mhz>;

+ pinctrl-2 = <&pinctrl_usdhc4_200mhz>;

+ cd-gpios = <&gpio3 21 GPIO_ACTIVE_LOW>;

+ vmmc-supply = <&reg_sd4_vmmc>;

+ vqmmc-1-8-v = <1>;

+ bus-width = <4>;

+ keep-power-in-suspend;

+ enable-sdio-wakeup;

+ status = "okay";

+};

The device tree compiles and if I use "broken-cd" the card is mounted properly

Hi Guillermo Moreno,

I have not run the newest version BSP, I will download it and do test. Then give you reply.

Have a nice day
