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 R8A73A4 (R-Mobile APE6) compatible PWM controller. 7 - "renesas,tpu-r8a7740": for R8A7740 (R-Mobile A1) compatible PWM controller. 8 - "renesas,tpu-r8a7743": for R8A7743 (RZ/G1M) compatible PWM controller. 9 - "renesas,tpu-r8a7745": for R8A7745 (RZ/G1E) compatible PWM controller. 10 - "renesas,tpu-r8a7790": for R8A7790 (R-Car H2) compatible PWM controller. 11 - "renesas,tpu": for generic R-Car and RZ/G1 TPU PWM controller. 12 13 - reg: Base address and length of each memory resource used by the PWM 14 controller hardware module. 15 16 - #pwm-cells: should be 3. See pwm.txt in this directory for a description of 17 the cells format. The only third cell flag supported by this binding is 18 PWM_POLARITY_INVERTED. 19 20Please refer to pwm.txt in this directory for details of the common PWM bindings 21used by client devices. 22 23Example: R8A7740 (R-Mobile A1) TPU controller node 24 25 tpu: pwm@e6600000 { 26 compatible = "renesas,tpu-r8a7740", "renesas,tpu"; 27 reg = <0xe6600000 0x148>; 28 #pwm-cells = <3>; 29 }; 30
