extcon: Remove optional print_state() function pointer of struct extcon_dev

2015-08-10T02:48:55+00:00

This patch removes the optional print_state() function pointer which included
in 'struct extcon_dev' because the extcon must maintain the consistent name
of extcon device on sysfs instead of inconsistent state of external connectors.

extcon: Remove the optional name of extcon device

2015-05-19T07:39:06+00:00

This patch removes the optional name of extcon device. Instead,
extcon_dev_register() set the device name as 'extcon[number]' naming pattern.
- /sys/class/extcon/[hardcoded device name] -> /sys/class/extcon/extcon[number]

extcon: gpio: Use devm_extcon_dev_register()

2014-04-24T10:37:03+00:00

Use the resource-managed extcon device register function (i.e.
devm_extcon_dev_register()) instead of extcon_dev_register(). If extcon device
is attached with this function, that extcon device is automatically unregistered
on driver detach. That reduces tiresome managing code.

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().
