5   - reg: Should contain physical base address and length of pwm registers.
6   - clocks: Must contain an entry for each entry in clock-names.
7         See ../clock/clock-bindings.txt for details.
8   - clock-names: Must include the following entries.
9     - pwm: PWM operating clock.
10     - sys: PWM system interface clock.
