Cover letter [PATCH 0/3] ARM: OMAP3/4: Correct support for PWM LEDs/backlight

Hi Tony,

Quoted 17 lines · Peter Ujfalusi

Hi,

The pwm-leds driver update is going for 3.9:
https://lkml.org/lkml/2012/12/21/99

This series will make sure that in 3.9 we are going to have working LEDs and backlight on these boards.

As a note: 4430SDP never had working backlight and the charger led did not worked for couple of releases already due to wrong pwm_id.

On BeagleBoard we will be able to adjust the brighness of pmu_stat LED instead of full on/off.

Zoom2 will have working keypad light and the backlight will be moved to be handled by the generic pwm-backlight driver.

This series will also fix a compile error in board-zoom-display.c caused by the changes in twl-core - which I missed :(

The DT support for these are going to be sent later.

Tony: can you apply this - if it looks OK - so it will hit linux-next before the second batch of twl-core update?

The series has been generated on top of my previous series for audio support update of omap-twl4030:

I can regenerate this without the depending series if you prefer that way.
