1	* Renesas R-Car Timer Pulse Unit PWM Controller
2	
3	Required 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	
19	Please refer to pwm.txt in this directory for details of the common PWM bindings
20	used by client devices.
21	
22	Example: R8A7740 (R-Car A1) TPU controller node
23	
24		tpu: pwm@e6600000 {
25			compatible = "renesas,tpu-r8a7740", "renesas,tpu";
26			reg = <0xe6600000 0x100>;
27			#pwm-cells = <3>;
28		};
