  ACPI / GPIO: Document ACPI GPIO mappings API
  net: rfkill: gpio: Add default GPIO driver mappings for ACPI
  ACPI / GPIO: Driver GPIO mappings for ACPI GPIOs
  input: gpio_keys_polled: Make use of device property API
  leds: leds-gpio: Make use of device property API
  gpio: Support for unified device properties interface
  Driver core: Unified interface for firmware node properties
  input: gpio_keys_polled: Add support for GPIO descriptors
  leds: leds-gpio: Add support for GPIO descriptors
  gpio: sch: Consolidate core and resume banks
  gpio / ACPI: Add support for _DSD device properties
  misc: at25: Make use of device property API
  ACPI: Allow drivers to match using Device Tree compatible property
  Driver core: Unified device properties interface for platform firmware
  ACPI: Add support for device specific properties
