leds-lm3530: support pwm input mode

2012-03-23T23:58:35+00:00

* add 'struct lm3530_pwm_data' in the platform data The pwm data is the platform specific functions which generate the pwm. The pwm data is only valid when brightness is pwm input mode. Functions should be implemented by the pwm driver. pwm_set_intensity() : set duty of pwm. pwm_get_intensity() : get current the brightness. * brightness control by pwm If the control mode is pwm, then brightness is changed by the duty of pwm=. So pwm platform function should be called in lm3530_brightness_set(). * do not update brightness register when pwm input mode In pwm input mode, brightness register is not used. If any value is updated in this register, then the led will be off. * when input mode is changed, set duty of pwm to 0 if unnecessary.
