Kernel-4.18.0-80.el8_img-pw

*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>;
};
