3 Required properties:
4 - compatible: Should be "img,pistachio-pwm"
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.
11 - #pwm-cells: Should be 2. See pwm.yaml in this directory for the
12 description of the cells format.
13 - img,cr-periph: Must contain a phandle to the peripheral control
14 syscon node which contains PWM control registers.

16 Example:
17 pwm: pwm@18101300 {
18 compatible = "img,pistachio-pwm";
19 reg = <0x18101300 0x100>;
20 clocks = <&pwm_clk>, <&system_clk>;
21 clock-names = "pwm", "sys";
22 #pwm-cells = <2>;
23 img,cr-periph = <&cr_periph>;
