[PATCH 0/5] ARM: dts: OMAP3+: PWM support for TWL and selected boards

[PATCH 0/5] ARM: dts: OMAP3+: PWM support for TWL and selected boards

[Peter Ujfalusi]

Hi,

Add the needed DT sections for twl4030 and twl6030 for the PWM childs.
Update the omap4-sdp to have working backlight and keypad/charging LED support.
Use the pwm-leds driver on BeagleBoard for the pmu_stat LED instead of the hacky
twl403-gpio mapped PWM.

Regards,
Peter
