[RFC PATCH 09/10] arm/dts: OMAP4: Add gpio nodes
Benoit Cousson

Wed Aug 24 23:09:15 EST 2011
Add the 6 GPIOs controller nodes.
Since the GPIO driver is still under cleanup, a couple of temp
hacks are needed. They will be removed as soon as the driver will
be cleaned.
Remove gpio static device initialisation if CONFIG_OF is defined.
