# RF switch subsystem configuration
#
menuconfig RFKILL
	tristate "RF switch subsystem support"
	help
	  Say Y here if you want to have control over RF switches
	  found on many WiFi and Bluetooth cards.

	  To compile this driver as a module, choose M here: the
	  module will be called rfkill.

# LED trigger support
config RFKILL_LEDS
	bool
	depends on RFKILL
	depends on LEDS_TRIGGERS = y || RFKILL = LEDS_TRIGGERS
	default y

config RFKILL_INPUT
	bool "RF switch input support" if EXPERT
	depends on RFKILL
	depends on INPUT = y || RFKILL = INPUT
	default y if !EXPERT

config RFKILL_REGULATOR
	tristate "Generic rfkill regulator driver"
	depends on RFKILL || !RFKILL
	depends on REGULATOR
	help
          This options enable controlling radio transmitters connected to
          voltage regulator using the regulator framework.

          To compile this driver as a module, choose M here: the module will
          be called rfkill-regulator.

config RFKILL_GPIO
	tristate "GPIO RFKILL driver"
	depends on RFKILL
	depends on GPIOLIB || COMPILE_TEST
	default n
	help
	  If you say yes here you get support of a generic gpio RFKILL
	  driver.
re spec says that "If there is an existing mapping for the EventID-DeviceID combination, behavior is UNPREDICTABLE"). While this could be worked around in each individual driver, it may make more sense to tackle the issue at the core level. In order to avoid getting in that situation, let's have a per-interrupt flag to remember if we have already activated that interrupt or not.
