> Pandora has some LEDs and backlights connected to OMAP
> GPIOs and TWL4030/TPS65950 LED/PWM signals. This patch
> registers them all with leds-gpio driver. TWL4030/TPS65950
> controlled ones will be switched to PWM driver when it's ready.
Pushing to l-o tree and adding to omap3-upstream queue for next
merge window. Not adding the defconfig changes to upstream queue
right now as the patch does not apply.
