[PATCH v18 0/3] Add OpenCores PTC PWM support

[Hal Feng]

Add OpenCores PTC PWM driver which is used in StarFive
JH7100/JH7110/JHB100 SoC.

I will maintain this pwm module in place of William.

Changes since v17:
- Simplify the code. Make it more readable.
- Restructure the driver to register the pwm chip for one pwm channel,
  because each OpenCores PTC IP core only supports one PWM channel.
  Drop starfive compatibles.
  Add patches to fix the dt-bindings and device tree.
- Support runtime pm and system sleep pm.
- Disable the pwm module and reset the pwm counter before updating the
  period and duty cycle.
- Improve the descriptions.
- Update the dt-bindings maintainer to Hal Feng.

v17: https://lore.kernel.org/all/20250106103540.10079-1-william.qiu@starfivetech.com/
