Hi friends,
I have my own carrier board design for eMMC version of imx6ull coreboard. I want to use SDIO1 for wifi instead of SD card. how can I do it? usually SDIO2 is used for wifi module.
how should I modify dts file? should I do any modification in driver?
you can see corresponding lines in dts file:
&usdhc1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc1>;
keep-power-in-suspend;
enable-sdio-wakeup;
non-removable;
bus-width = <4>;
status = "okay";
};
&usdhc2 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc2>;
non-removable;
status = "disabled";
};
.
.
.
pinctrl_usdhc1: usdhc1grp {
fsl,pins = <
MX6UL_PAD_SD1_CMD__USDHC1_CMD 0x17059
MX6UL_PAD_SD1_CLK__USDHC1_CLK 0x10071
MX6UL_PAD_SD1_DATA0__USDHC1_DATA0 0x17059
MX6UL_PAD_SD1_DATA1__USDHC1_DATA1 0x17059
MX6UL_PAD_SD1_DATA2__USDHC1_DATA2 0x17059

>;
};
