[PATCH 0/2] Input: gpio-keys: support for disabling GPIOs

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

Hi Dmitry,

This is a third proposal for disabling individual GPIO keys. Now I
implemented this as you suggested. There are now 4 new attributes
under sys/devices/platform/gpio-keys/:
	keys - keys that can be disabled (by keycode)
	switches - switches that can be disabled (by switch code)
	disabled_keys - keys that are currently disabled
	disabled_switches - switches that are currently disabled

I added those 2 attributes (keys and switches) so that userland
can find out what keys/switches are available. Hope this is OK
for you.

These are exported as bitmaps as you suggested (using
bitmap_scnlistprintf() and bitmap_parselist()).

Patches were made against branch 'next'. If these patches get accepted
I'll prepare patch for RX-51 (probably send it to linux-omap ml) where
GPIO buttons don't allow sharing the IRQ.

I tested this with RX-51.

Thanks,
MW
