> devicetree bindings and its documentation.
>
> Changes since v1:
> - Fixed commit message for the dt-bindings doc
> - Removed "OneOf" from the dt-bindings doc
> - Re-ordered alphabetically in Kconfig and remove
>   unseless empty lines
> - Explain and adds comment in _writecounter() (hw
>   constrainst)
> - Reworked the msc313e_pwm_config() function
> - Fixed clk handling
> - Removed extra callbacks, only keep .apply and .get_state
> - Implement .get_state completly, this fixes the driver with PWM_DEBUG
>   (the whole driver has been tested with PWM_DEBUG).
> - Dropped useless lines in _probe
> - I have kept regmap_field() because it is more clean and helpful, it
>   avoids to do too much of offset and mask and shift all over the place.
