Rongjun Ying 6544dfa579 extcon: gpio: Add power resume support
When system on the suspend state, Some SoC can't get gpio interrupt.
After system resume, need send extcon uevent to userspace.

Guenter Roeck 4288d9b8ed extcon: gpio: Request gpio pin before modifying its state
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().

Chanwoo Choi 42d7d7539a extcon: Simplify extcon_dev_register() prototype by removing unnecessary parameter
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().

Jingoo Han 7c0f6558f8 extcon: use dev_get_platdata()
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.

Mark Brown d0db2e7ae7 extcon: gpio: Use power efficient workqueue for debounce
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.
