extcon: gpio: Add power resume support

2014-01-09T00:53:30+00:00

When system on the suspend state, Some SoC can't get gpio interrupt.
After system resume, need send extcon uevent to userspace.

extcon: gpio: Request gpio pin before modifying its state

2014-01-07T02:54:26+00:00

Commit 338de0ca (extcon: gpio: Use gpio driver/chip debounce if supported)
introduced a call to gpio_set_debounce() before actually requesting the
respective gpio pin from the gpio subsystem.

The gpio subsystem expects that a gpio pin was requested before modifying its
state. Not doing so results in a warning from gpiolib, and the gpio pin is
auto-requested. This in turn causes the subsequent devm_gpio_request_one()
to fail. So devm_gpio_request_one() must be called prior to calling
gpio_set_debounce().

extcon: Simplify extcon_dev_register() prototype by removing unnecessary parameter

2013-09-27T00:37:01+00:00

This patch remove extcon_dev_register()'s second parameter which means
the pointer of parent device to simplify prototype of this function.
So, if extcon device has the parent device, it should set the pointer of
parent device to edev.dev.parent in extcon device driver instead of in
extcon_dev_register().

extcon: gpio: Add support for active-low presence to detect pins

2013-09-27T00:37:01+00:00

This patch add 'gpio_active_low' field to 'struct gpio_extcon_data'
to check whether gpio active state is 1(high) or 0(low).

extcon: use dev_get_platdata()

2013-09-27T00:37:01+00:00

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly. This is a cosmetic change
to make the code simpler and enhance the readability.

extcon: gpio: Use power efficient workqueue for debounce

2013-08-04T23:53:34+00:00

The debounce timeout is generally quite long and the work not performance
critical so allow the scheduler to run the work anywhere rather than in
the normal per-CPU workqueue.

extcon: remove use of __devexit_p

2012-11-26T23:57:24+00:00

CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer
needed.
