22- reg: base address and length of the registers block for the PWM.
23- #pwm-cells: should be 2. See pwm.txt in this directory for a description of
24 the cells format.
25- clocks: clock phandle and specifier pair.
26- pinctrl-0: phandle, referring to a default pin configuration node.
27- pinctrl-names: Set to "default".
