  1. * Renesas R-Car Timer Pulse Unit PWM Controller
  2. Required Properties:
  3. - compatible: should be one of the following.
  4. - "renesas,tpu-r8a73a4": for R8A73A4 (R-Mobile APE6) compatible PWM controller.
  5. - "renesas,tpu-r8a7740": for R8A7740 (R-Mobile A1) compatible PWM controller.
  6. - "renesas,tpu-r8a7743": for R8A7743 (RZ/G1M) compatible PWM controller.
  7. - "renesas,tpu-r8a7745": for R8A7745 (RZ/G1E) compatible PWM controller.
  8. - "renesas,tpu-r8a7790": for R8A7790 (R-Car H2) compatible PWM controller.
  9. - "renesas,tpu": for generic R-Car and RZ/G1 TPU PWM controller.
  10. - reg: Base address and length of each memory resource used by the PWM
  11. controller hardware module.
  12. - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
  13. the cells format. The only third cell flag supported by this binding is
  14. PWM_POLARITY_INVERTED.
  15. Please refer to pwm.txt in this directory for details of the common PWM bindings
  16. used by client devices.
  17. Example: R8A7740 (R-Mobile A1) TPU controller node
  18. tpu: pwm@e6600000 {
  19. compatible = "renesas,tpu-r8a7740", "renesas,tpu";
  20. reg = <0xe6600000 0x148>;
  21. #pwm-cells = <3>;
  22. };
