    pinctrl_usdhc2_sbc: usdhc2-sbc-grp-1 {
	fsl,pins = <
		MX6QDL_PAD_SD2_CMD__SD2_CMD    0x16058
		MX6QDL_PAD_SD2_CLK__SD2_CLK    0x16058
		MX6QDL_PAD_SD2_DAT0__SD2_DATA0 0x16058
		MX6QDL_PAD_SD2_DAT1__SD2_DATA1 0x16058
			MX6QDL_PAD_SD2_DAT2__SD2_DATA2 0x16058
			MX6QDL_PAD_SD2_DAT3__SD2_DATA3 0x16058
	>;
    };
