BACKPORT: FROMLIST: pwm: Add support for different PWM output types Normally, PWM channels have fixed output until software requests to change their settings. There are some PWM devices whose outputs can be changed autonomously according to a predefined pattern programmed in hardware. Add support for such devices by adding a new pwm_output_type enum type to identify these two different PWM types and adding helper functions to read the PWM output type supported by a PWM.
