Hi,
- Port Linux apply API to make porting future PWM drivers easier
- Remove duplicated PWM state, so device variables can be used to query
and influence actual configuration
- Add support for PWM polarity
- Add support for STM32
Cheers,
Ahmad Fatoum (12):
led: pwm: always initialize PWM LEDs as inactive
PWM: core: remove FLAG_ENABLED
PWM: core: remove ineffectual pwm_{set,get}_duty_cycle
PWM: core: group PWM state into new struct pwm_state
PWM: core: remove old PWM API in favor of Linux ->apply
PWM: core: retire pwm_set_period
PWM: core: apply initial state in of_pwm_request
video: backlight-pwm: use new pwm_apply_state API
led: pwm: use new pwm_apply_state API
PWM: core: add apply API support for polarity
of: introduce of_property_count_elems_of_size
PWM: add support for STM32
