Subject: [PATCH v2 0/3] pwm: Drivers for twl4030/6030 PWMs and LEDs

Hello,

Changes cince v1:
- The turn on/off sequence has been corrected for twl4030 PWMs as suggested by
  Grazvydas Ignotas
- Comment section added to the new drivers to describe what they are controlling

The series has been tested (with additional, pending patches):
Zoom2 for twl4030 PWM0 (keypad light), PWM1 (LCD backlight)
BeagleBoard for twl4030 LEDB (PWMB - pmu_stat led)
OMAP4 Blaze (SDP4430) for twl6030 PWM1 (keypad light), PWM2 (LCD backlight) and
LED (charging indication led).

Intro mail from v1:

The currently available pwm-twl6030.c driver only supports TWL6030's Charging
indication LED.
Remove this driver and add two new ones which implements support for all PWM
driven outputs:
pwm-twl driver supports twl4030 (PWM 0/1) and twl6030 (PWM 1/2) instances
pwm-twl-led driver supports twl4030 (PWM driven LED A/B ports) and twl6030's
Charging indication LED (PWM driven).

Regards,
Peter
