SD-CARD USDHC2 not working in lf-5.15.y_var01 linux-variscite branch

CrazyDeveloper

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#**
