Team,
I am trying to connect uSD Adapter Fixed 3.3 V rev A board to micro SD slot of IMX8MM MINI LPD4-CPU2. on the muratha board i am connecting CYW54591.
Following are the DTS changes i am doing
&usdhc2{
compatible = "fsl,imx6q-usdhc";
reg = <0x02194000 0x4000>;
interrupts = <0 23 0x04>;
clocks = <&clks 164>, <&clks 164>, <&clks 164>;
clock-names = "ipg", "ahb", "per";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc2_1>;
cd-gpios = <&gpio2 2 0>;
wp-gpios = <&gpio2 3 0>;
bus-width = <8>;
no-1-8-v;
non-removable;
mmc-pwrseq = <&usdhc2_pwrseq>;
pm-ignore-notify;
cap-power-off-card;
// keep-power-in-suspend;
enable-sdio-wakeup;
mmc-hs200-1_8v;
mmc-hs400-1_8v;
bus-width = <8>;
status = "okay";
brcmf: bcrmf@1 {
reg = <1>;
compatible = "brcm,bcm4329-fmac";
};
};
I am getting the following error message:

Request you to guide me if the MicroSD slot on Imx8mm mini evk board supports sdmmc/ reconfiguration of SDIO.
