[RFC PATCH 0/1] Enabling/disabling separate gpio-keys buttons

[Mika Westerberg <ext-mika.1.westerberg@nokia.com>]

Some embedded devices use gpio lines as keys/buttons through gpio-keys.
Current implementation doesn't allow one to enable/disable these buttons
separately.

Example use-case would be that when phone is locked in our pocket,
we don't want it to woken up when camera key gets accidentally pressed.

Following patch exports gpio-keys through sysfs to userland and allows
userland programs to control whether gpio line (button/key) is disabled
or enabled.

Thanks,
MW
