Chanwoo Choi6ba12992015-09-29 22:59:55 +090026 * struct gpio_extcon_pdata - A simple GPIO-controlled extcon device.
Chanwoo Choice6f7492015-09-29 22:57:24 +090027 * @extcon_id: The unique id of specific external connector.
Chanwoo Choia75e1c72013-08-31 13:16:49 +090028 * @gpio: Corresponding GPIO.
Guenter Roeck5bfbdc92013-09-12 08:49:54 +090029 * @gpio_active_low: Boolean describing whether gpio active state is 1 or 0
30 * If true, low state of gpio means active.
31 * If false, high state of gpio means active.
Chanwoo Choia75e1c72013-08-31 13:16:49 +090032 * @debounce: Debounce time for GPIO IRQ in ms.
33 * @irq_flags: IRQ Flags (e.g., IRQF_TRIGGER_LOW).
George Cherian62364352014-09-09 09:44:34 +053034 * @check_on_resume: Boolean describing whether to check the state of gpio
35 * while resuming from sleep.
