Adding GPIO in device tree error for imx8m mini evk board.

i added

&iomuxc {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_hog_1>;

imx8mm-evk {
pinctrl_hog_1: hoggrp-1 {
fsl,pins = <
MX8MM_IOMUXC_GPIO1_IO08_GPIO1_IO8 0x19
MX8MM_IOMUXC_SAI5_RXD3_GPIO3_IO24 0x41

>;
};

pinctrl_csi_pwn: csi_pwn_grp {
fsl,pins = <
MX8MM_IOMUXC_GPIO1_IO07_GPIO1_IO7 0x19
>;
};

}

in path arch/arm64/boot/dts/freescale//imx8mm-evk.dts

Error created while building is attached below

The screenshot of added and screenshot where the error is showing

Thanks in advance
