* Renesas R-Car Timer Pulse Unit PWM Controller
|
|
|
|
Required Properties:
|
|
|
|
- compatible: must contain one or more 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-r8a7744": for R8A7744 (RZ/G1N) 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-r8a77970": for R8A77970 (R-Car V3M) compatible PWM
|
|
controller.
|
|
- "renesas,tpu-r8a77980": for R8A77980 (R-Car V3H) compatible PWM
|
|
controller.
|
|
- "renesas,tpu": for the generic TPU PWM controller; this is a fallback for
|
|
the entries listed above.
|
|
|
|
- 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>;
|
|
};
