1* Renesas R-Car Timer Pulse Unit PWM Controller
2
3Required Properties:
4
5  - compatible: should be one of the following.
6    - "renesas,tpu-r8a73a4": for R8A77A4 (R-Mobile APE6) compatible PWM controller.
7    - "renesas,tpu-r8a7740": for R8A7740 (R-Mobile A1) compatible PWM controller.
8    - "renesas,tpu-r8a7790": for R8A7790 (R-Car H2) compatible PWM controller.
9    - "renesas,tpu-sh7372": for SH7372 (SH-Mobile AP4) compatible PWM controller.
10    - "renesas,tpu": for generic R-Car TPU PWM controller.
11
12  - reg: Base address and length of each memory resource used by the PWM
13    controller hardware module.
14
15  - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
16    the cells format. The only third cell flag supported by this binding is
17    PWM_POLARITY_INVERTED.
18
19Please refer to pwm.txt in this directory for details of the common PWM bindings
20used by client devices.
