Subject: [PATCH v2 0/5] Add PWM for MStar SoCs

This patches series adds a new driver for the PWM found in the Mstar
MSC313e SoCs and newer. It adds a basic pwm driver, the corresponding
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.
