parentInput: mark input interfaces as non-seekable (diff)
Input: gpio-keys - add support for disabling gpios through sysfs
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>
