Intel's LGM(Lightning Mountain) SoC contains a PWM fan controller
which is only used to control the fan attached to the system. This
PWM controller does not have any other consumer other than fan.
Add DT bindings documentation for this PWM fan controller.

My bot found errors running 'make dt_binding_check' on your patch:

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/reset/intel,rcu-gw.example.dt.yaml: pwm@e0d00000: '#pwm-cells' does not match any of the regexes: 'pinctrl-[0-9]+'
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/pwm/intel,lgm-pwm.example.dt.yaml: pwm@e0d00000: '#pwm-cells' is a required property


See https://patchwork.ozlabs.org/patch/1334579

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.
