11 | - reg: physical base address and length of the controller's registers. |
12 | - #pwm-cells: must be 2. See pwm.txt in this directory for a description of | |
13 | the cell format. | |

15 | - clock-names: must contain the following, except for MT7628 which |
16 | has no clocks | |

17 | - "top": the top clock generator |
18 | - "main": clock used by the PWM core | |
62843a61 ZM |
19 | - "pwm1-8": the eight per PWM clocks for mt2712 |
20 | - "pwm1-6": the six per PWM clocks for mt7622 | |
21 | - "pwm1-5": the five per PWM clocks for mt7623 | |

22 | - pinctrl-names: Must contain a "default" entry. |
23 | - pinctrl-0: One property must exist for each entry in pinctrl-names. | |
24 | See pinctrl/pinctrl-bindings.txt for details of the property values. | |
