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-rc2.

v3:
- Address below review concerns from Uwe Kleine-König.
  * Improve notes and limitations comments.
  * Add common prefixes for all #defines.
  * Modify/Improve logic in .apply & .get_state ops as advised.
  * Skip error messages in probe when error is -EPROBE_DEFER.
  * Add dependencies in Kconfig (OF & HAS_IOMEM) and add select REGMAP_MMIO.
  * Address other code quality related review concerns.
- Fix make dt_binding_check reported error in YAML file.

v3:
- Address below review concerns from Uwe Kleine-König.
  * Remove fan rpm calibration task from the driver.
  * Modify apply op as per the review feedback.
  * Add roundup & round down where necessary.
  * 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-König.
  * Add notes and limitations about PWM HW.
  * Rename all functions and structure to lgm_pwm_* 
  * Readjust space aligninment in structure fields to single space.
  * Switch to using apply instead of config/enable/disable.
  * Address other code quality related concerns.
  * Rebase to 5.8-rc1.
- Address review concerns in dt binding YAML from Rob Herring.

v1:
- Initial version.

Rahul Tanwar (2):
