Hi,
You can't seem to use:
gpio = <&gpio1 0 0>;
inside of:
reg_usb_otg_vbus: usb_otg_vbus {
because that equates to a value of zero in config->ena_gpio
in drivers/regulator/core.c:
if (config->ena_gpio && gpio_is_valid(config->ena_gpio)) {
which means it won't drop into the if statement. I think I have a fix
but it's a bit invasive, touches a lot of files. The gist is changing:
struct regulator_config cfg = { };
to
struct regulator_config cfg = { .ena_gpio = -ENODEV, }; /* set to
invalid, we we can use zero */
and changing:
if (whatever->ena_gpio)
to:
if (gpio_is_valid(whatever->ena_gpio))
Maybe someone has a better idea...
Cheers,
Rick
