Subject: [RFT PATCH 0/4] platform/x86: int3472: don't use gpiod_toggle_active_low()

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

gpiod_toggle_active_low() is a badly designed API that should have never
been used elsewhere then in the MMC code. And even there we should find
a better solution.

Replace the uses of it in the int3472 driver with the good old temporary
lookup table trick. This is not very pretty either but it's the lesser
evil.

Bartosz Golaszewski (4):
  platform/x86: int3472: provide a helper for getting GPIOs from lookups
  platform/x86: int3472: led: don't use gpiod_toggle_active_low()
  platform/x86: int3472: clk_and_regulator: use GPIO lookup tables
  gpio: acpi: remove acpi_get_and_request_gpiod()
