Kernel-4.18.0-80.el8_renesas,tpu-pw

• Renesas R-Car Timer Pulse Unit PWM Controller

Required Properties:

• compatible: should be one of the following.

  • “renesas,tpu-r8a73a4”: for R8A73A4 (R-Mobile APE6) compatible PWM controller.
  • “renesas,tpu-r8a7740”: for R8A7740 (R-Mobile A1) compatible PWM controller.
  • “renesas,tpu-r8a7743”: for R8A7743 (RZ/G1M) compatible PWM controller.
  • “renesas,tpu-r8a7745”: for R8A7745 (RZ/G1E) compatible PWM controller.
  • “renesas,tpu-r8a7790”: for R8A7790 (R-Car H2) compatible PWM controller.
  • “renesas,tpu”: for generic R-Car and RZ/G1 TPU PWM controller.

• reg: Base address and length of each memory resource used by the PWM
  controller hardware module.

• #pwm-cells: should be 3. See pwm.txt in this directory for a description of
  the cells format. The only third cell flag supported by this binding is
  PWM_POLARITY_INVERTED.

Please refer to pwm.txt in this directory for details of the common PWM bindings
used by client devices.

Example: R8A7740 (R-Mobile A1) TPU controller node

tpu: pwm@e6600000 {
    compatible = "renesas,tpu-r8a7740", "renesas,tpu";
    reg = <0xe6600000 0x148>;
    #pwm-cells = <3>;
};
