Patch 1 adds dt binding document in YAML format.
Patch 2 add PWM fan controller driver for LGM SoC.

v11:
- Address below review concerns (Andy Shevchenko)
  * Fix a issue with dev_err_probe() usage & improve the usage.
  * Fix & improve a ordering issue with clk_enable/disable &
    reset_control assert/deassert.

v10:
- Removed unused of_device.h and added platform_device.h
  & mod_devicetable.h

v9:
- Address code quality related review concerns (Andy Shevchenko)
- Use devm_add_action_or_reset() instead of explicit unwind calls.

v8:
- Remove fan related optional properties usage, keep
  them as default. If needed, change pwm-fan driver
  separately in future to add them as generic properties.

v7:
- Address code quality related review concerns.
- Rename fan related property to pwm-*.
- Fix one make dt_binding_check reported error.

v6:
- Readjust .apply op as per review feedback.
- Add back pwm-cells property to resolve make dt_binding_check error.
  pwm-cells is a required property for PWM driver.
- Add back fan related optional properties.

v5:
- Address below review concerns from Uwe Kleine-K?nig.
  * 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?nig.
  * 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-K?nig.
  * 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-K?nig.
  * 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.
