we are adding a sdio wifi module in MX8M EVK, and android 8.1 is installed on evk board.
we plan to add two pins (GPIO4_IO12 ,GPIO4_IO13) , GPIO4_IO12 for WL_WAKE and GPIO4_IO13 is for WL_REGON,
detailed dtsi is below, could you tell how to config these two pins? that is to say, how to add gpio to &iomuxc?
regulators {
wlreg_on: fixedregulator@100 {
compatible = "regulator-fixed";
regulator-name = "wlreg_on";
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
gpio = <&gpio4 13 0>;
startup-delay-us = <100>;
enable-active-high;
};
};
bcmdhd_wlan_0: bcmdhd_wlan@0 {
compatible = "android,bcmdhd_wlan";
bcmdhd_fw = "/vendor/firmware/bcm/fw_bcmdhd.bin";
bcmdhd_nv = "/vendor/firmware/bcm/bcmdhd.cal";
gpios = <&gpio4 12 0>; /* WL_HOST_WAKE */
wlreg_on-supply = <&wlreg_on>;
};
thanks
