On this board, GPIO91 is wired as a common enable for both WiFi
power rails: WiFi 1.8V and WiFi 3.85V.
I currently modeled them as two regulator-fixed nodes because these
are two distinct rails.
Would you prefer modelling a single regulator node that controls the
shared GPIO as below:
wifi_en: regulator-wifi-en {
compatible = "regulator-fixed";
regulator-name = "wifi_en";
gpio = <&tlmm 91 GPIO_ACTIVE_HIGH>;
enable-active-high;
pinctrl-0 = <&wifi_reg_en_pins_state>;
pinctrl-names = "default";
regulator-boot-on;
regulator-always-on;
};
