0001 *Imagination Technologies PWM DAC driver
0002
0003 Required properties:
0004 - compatible: Should be "img,pistachio-pwm"
0005 - reg: Should contain physical base address and length of pwm registers.
0006 - clocks: Must contain an entry for each entry in clock-names.
0007 See ../clock/clock-bindings.txt for details.
0008 - clock-names: Must include the following entries.
0009 - pwm: PWM operating clock.
0010 - sys: PWM system interface clock.
0011 - #pwm-cells: Should be 2. See pwm.yaml in this directory for the
0012 description of the cells format.
0013 - img,cr-periph: Must contain a phandle to the peripheral control
0014 syscon node which contains PWM control registers.

0016 Example:
0017 pwm: pwm@18101300 {
0018 compatible = "img,pistachio-pwm";
0019 reg = <0x18101300 0x100>;
0020 clocks = <&pwm_clk>, <&system_clk>;
0021 clock-names = "pwm", "sys";
0022 #pwm-cells = <2>;
0023 img,cr-periph = <&cr_periph>;
0024 };
