Commit Message

Hans de Goede Oct. 4, 2023, 4:23 p.m. UTC 
Use the new skl_int3472_gpiod_get_from_temp_lookup() helper to get
a gpio to pass to register_gpio_clock(), skl_int3472_register_regulator()
and skl_int3472_register_pled().

This removes all use of the deprecated gpiod_toggle_active_low() and
acpi_get_and_request_gpiod() functions.
