*Imagination Technologies PWM DAC driver
Required properties:
- compatible: Should be "img,pistachio-pwm"
- reg: Should contain physical base address and length of pwm registers.
- clocks: Must contain an entry for each entry in clock-names.
See ../clock/clock-bindings.txt for details.
- clock-names: Must include the following entries.
- pwm: PWM operating clock.
- sys: PWM system interface clock.
- #pwm-cells: Should be 2. See pwm.txt in this directory for the
description of the cells format.
- img,cr-periph: Must contain a phandle to the peripheral control
syscon node which contains PWM control registers.
Example:
pwm: pwm@18101300 {
compatible = "img,pistachio-pwm";
reg = <0x18101300 0x100>;
clocks = <&pwm_clk>, <&system_clk>;
clock-names = "pwm", "sys";
#pwm-cells = <2>;
img,cr-periph = <&cr_periph>;
};
