New PWM drivers are being prepared for twl series which will enable the use of all PWMs (PWMs and LEDs). They are implemented as generic PWM drivers to be able to use them for different purposes. The current platform code was broken: the leds_pwm driver was not able to pick up the PWM since the pwm_id was incorrect. With the other patches we will be able to control the followings: LCD backlight via pwm-backlight driver Keypad leds via leds_pwm driver as normal LED Charging indicator via leds_pwm driver as normal LED Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com>
