- reg: Base address and length of each memory resource used by the PWM
controller hardware module.
- #pwm-cells: should be 3. See pwm.txt in this directory for a description of
the cells format. The only third cell flag supported by this binding is
PWM_POLARITY_INVERTED.
Please refer to pwm.txt in this directory for details of the common PWM bindings
used by client devices.
