Patch 1 adds dt binding document in YAML format.
Patch 2 add PWM fan controller driver for LGM SoC.
Patch series is baselined on linux 5.8-rc5.
v5:
- Address below review concerns from Uwe Kleine-K�.
* Improve comments about Limitations.
* Use return value of regmap_update_bits if container function returns
error code.
* Modify .apply op to have strict checking for fixed period supported
by PWM HW.
* Use u64 as type when use min_t for duty_cycle.
* Add reset_control_assert() in failure case in probe where it was missing
earlier.
- Remove fan specific optional properties from pwm dt binding document (Rob Herring)
v4:
- Address below review concerns from Uwe Kleine-K�.
* Improve notes and limitations comments.
* Add common prefixes for all #defines.
* Modify/Improve logic in .apply & .get_state ops as advised.

* Address other misc code quality related review concerns.
* Use devm_reset_control_get_exclusive(). (Philipp Zabel)
* Improve dt binding document.
v2:
- Address below review concerns from Uwe Kleine-K�.
* Add notes and limitations about PWM HW.
* Rename all functions and structure to lgm_pwm_*
* Readjust space aligninment in structure fields to single space.
