+* 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
+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>;
