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.

During resume, gpio-keys does not get updated state of gpios which fails to report wakeup key event. Update resume routine to report key event based on wakeup source.

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.

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>
