Extcon: support generic GPIO extcon driver
The generic GPIO extcon driver (an external connector device based on GPIO control) and imported from Android kernel. switch: switch class and GPIO drivers. (splitted) Author: Mike Lockwood <lockwood@android.com> switch: gpio: Don't call request_irq with interrupts disabled Author: Arve Hjønnevåg <arve@android.com> switch_gpio: Add missing #include <linux/interrupt.h> Author: Mike Lockwood <lockwood@android.com> Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Reviewed-by: Mark Brown <broonie@opensource.wolfsonmicro.com> -- Changed from v7: - Style updates mentioned by Stephen Boyd and Mark Brown Changed from v5: - Splitted at v5 from the main extcon patch. - Added debounce time for irq handlers. - Use request_any_context_irq instead of request_irq - User needs to specify irq flags for GPIO interrupts (was fixed to IRQF_TRIGGER_LOW before) - Use module_platform_driver().
