* input: gpio_keys_polled: Add support for GPIO descriptorsAaron Lu2014-11-041-0/+3
| | | | | | | | | | | | | | | GPIO descriptors are the preferred way over legacy GPIO numbers nowadays. Convert the driver to use GPIO descriptors internally but still allow passing legacy GPIO numbers from platform data to support existing platforms.

* Input: gpio_keys - convert struct descriptions to kernel-docAndy Shevchenko2014-05-141-12/+36
| | | | | | | | | | | This patch converts descriptions of the structures defined in linux/gpio_keys.h to follow kernel-doc format. There is no functional change.

* Input: gpio_keys - add support for interrupt only keysLaxman Dewangan2012-03-191-1/+2
| | | | | | | | | | | Some of buttons, like power-on key or onkey, may only generate interrupts when pressed and not actually be mapped as gpio in the system. Allow setting gpio to invalid value and specify IRQ instead to support such keys. The debounce timer is used not to debounce but to ignore new IRQs coming while button is kept pressed.

* Input: gpio_keys - fix struct device declared inside parameter listHeiko Stübner2012-02-011-0/+2
| | | | | | | | | | | A struct device parameter is used in the enable and disable callbacks to distinguish between different gpio_keys devices. Platforms that don't use these callbacks may not include struct device at all, as seen on arch/arm/mach-s3c2410/mach-n30.c Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* Input: add input driver for polled GPIO buttonsGabor Juhos2010-12-061-0/+2
| | | | | | | | | | | | | | | | | The existing gpio-keys driver can be usable only for GPIO lines with interrupt support. Several devices have buttons connected to a GPIO line which is not capable to generate interrupts. This patch adds a new input driver using the generic GPIO layer and the input-polldev to support such buttons.

* Input: gpio-keys - add support for disabling gpios through sysfsMika Westerberg2010-02-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Now gpio-keys input driver exports 4 new attributes to userland through sysfs: /sys/devices/platform/gpio-keys/keys [ro] /sys/devices/platform/gpio-keys/switches [ro] /sys/devices/platform/gpio-keys/disabled_keys [rw] /sys/devices/platform/gpio-keys/disables_switches [rw] With these attributes, userland program can read which keys and switches can be disabled and then disable/enable them as needed. Keys and switches are exported as stringified bitmap of codes (keycodes or switch codes). For example keys 15, 89, 100, 101, 102 are exported as: '15,89,100-102'. Description of the attributes: keys - bitmap of keys which can be disabled switches - bitmap of switches which can be disabled disabled_keys - bitmap of currently disabled keys (bit 1 means disabled, 0 enabled) disabled_switches - bitmap of currently disabled switches (bit 1 means disabled, 0 enabled) Signed-off-by: Mika Westerberg <ext-mika.1.westerberg@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* [PATCH] gpio_keys driver shouldn't be ARM-specificDavid Brownell2007-03-051-0/+17
The gpio_keys driver is wrongly ARM-specific; it can't build on other platforms with GPIO suport. This fixes that problem.
