extcon: gpio: Fix code cleanup

2014-09-22T07:48:47Z

This patch fixes following minor cleanup: - Order the include files in alphabetical order. - Fix description of state_off in extcon_gpio.h - Add a descrition for check_on_resume in extcon_gpio.h Signed-off-by: George Cherian [Modify the name/description of patch to keep standary codiyg style by Chanwoo Choi] Signed-off-by: Chanwoo Choi

extcon: max77693: Fix a bug occured at changing ADC debounce time.

2014-09-22T07:14:58Z

When it writes some value other than 0 to BTLDset and JIGset, muic device will be reset automatically. And it happens during updating ADC debounce time, because it shares same register. To update ADC debounce time without reset, set value only to ADCDbset and 0 to BTLDset and JIGset.

extcon: max77693: Use resource managed interrupt line

2014-09-22T06:53:23Z

Use resource managed interrupt line devm_request_threaded_irq() to simplify a little cleanup paths: - no goto to cleanup label, - simpler remove function. Overall the driver size is decreased by 11 line of code. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Chanwoo Choi

extcon: rt8973a: Add Richtek RT8973A extcon driver

2014-09-22T02:43:08Z

This patch add support for Richtek RT8973A which is Micro USB Switch OVP and i2c interface. The RT8973A is a USB port accessory detector and switch that is optimized to protect low voltage system from abnormal high input voltage (up to 28V) and supports high speed USB operation. Also, RT8973A support 'auto-configuration' mode. If auto-configuration mode is enabled, RT8973A would control internal h/w patch for USB D-/D+ switching.
