This driver helps to register the device of GPIO based IR receiver, "gpio-ir-recv", with the gpio number and pulse trigger when driver is loading. For example, # modprobe gpio-ir-recv # modprobe gpioplug-ir-recv gpio_nr=24 active_low=1 Change-Id: Icc0ac0df04a1b4aa1d55ccfada48f686f6d0f109 Signed-off-by:
