USDHC2 not working in lf-5.15.y_var01 branch #26

Closed Muhammadhassan1234 closed 1 month ago

Muhammadhassan1234 commented 1 month ago

Hello! I was working on 5.4-2.1.x-imx_var01 branch and both my emmc and my external sd card was working fine. However, I updated my kernel to lf-5.15.y_var01 and my sdcard stopped working. Here are the usdhc2 nodes that I am using for both kernel versions. However, it is working in 5.4-2.1.x-imx_var01 but not in lf-5.15.y_var01. I have attached the device tree node overlay and logs below. Please tell me where is the problem!


#include "imx6dl-var-som-solo.dtsi"
/* uSDHC2, MMC/SD card */
&usdhc2 {   
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_usdhc2>, <&pinctrl_usdhc2_gpio>;
    cd-gpios = <&gpio4 14 GPIO_ACTIVE_LOW>;
    keep-power-in-suspend;
    enable-sdio-wakeup;
    status = "okay";
};

&iomuxc {
 imx6qdl-var-som-mx6 {

    pinctrl_usdhc2_gpio: usdhc2gpiogrp {
        fsl,pins = <
            /* SDMMC2 CD */
            MX6QDL_PAD_KEY_COL4__GPIO4_IO14         0x80000000
        >;
    };
 };
};

In 5.4-2.1.x-imx_var01, It detects all mmc on var-som-mx6 as show in kernel logs below#
