* Renesas R-Car Timer Pulse Unit PWM Controller
|
|
|
|
Required Properties:
|
|
|
|
- compatible: should be one of the following.
|
|
- "renesas,tpu-r8a73a4": for R8A77A4 (R-Mobile APE6) compatible PWM controller.
|
|
- "renesas,tpu-r8a7740": for R8A7740 (R-Mobile A1) compatible PWM controller.
|
|
- "renesas,tpu-r8a7790": for R8A7790 (R-Car H2) compatible PWM controller.
|
|
- "renesas,tpu-sh7372": for SH7372 (SH-Mobile AP4) compatible PWM controller.
|
|
- "renesas,tpu": for generic R-Car 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-Car A1) TPU controller node
|
|
|
|
tpu: pwm@e6600000 {
|
|
compatible = "renesas,tpu-r8a7740", "renesas,tpu";
|
|
reg = <0xe6600000 0x100>;
|
|
#pwm-cells = <3>;
|
|
};
