1* Renesas R-Car Timer Pulse Unit PWM Controller
2
3Required Properties:
4
5  - compatible: must contain one or more of the following:
6    - "renesas,tpu-r8a73a4": for R8A73A4 (R-Mobile APE6) compatible PWM controller.
7    - "renesas,tpu-r8a7740": for R8A7740 (R-Mobile A1) compatible PWM controller.
8    - "renesas,tpu-r8a7743": for R8A7743 (RZ/G1M) compatible PWM controller.
9    - "renesas,tpu-r8a7744": for R8A7744 (RZ/G1N) compatible PWM controller.
10    - "renesas,tpu-r8a7745": for R8A7745 (RZ/G1E) compatible PWM controller.
11    - "renesas,tpu-r8a7790": for R8A7790 (R-Car H2) compatible PWM controller.
12    - "renesas,tpu-r8a77970": for R8A77970 (R-Car V3M) compatible PWM
13			      controller.
14    - "renesas,tpu-r8a77980": for R8A77980 (R-Car V3H) compatible PWM
15			      controller.
16    - "renesas,tpu": for the generic TPU PWM controller; this is a fallback for
17		     the entries listed above.
18
19  - reg: Base address and length of each memory resource used by the PWM
20    controller hardware module.
21
22  - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
23    the cells format. The only third cell flag supported by this binding is
24    PWM_POLARITY_INVERTED.
25
26Please refer to pwm.txt in this directory for details of the common PWM bindings
27used by client devices.
