7   - "mediatek,mt7622-pwm": found on mt7622 SoC.
8   - "mediatek,mt7623-pwm": found on mt7623 SoC.
9   - "mediatek,mt7628-pwm": found on mt7628 SoC.
10   - "mediatek,mt7629-pwm": found on mt7629 SoC.
11   - "mediatek,mt8183-pwm": found on mt8183 SoC.

14   - "mediatek,mt8516-pwm": found on mt8516 SoC.
15 - reg: physical base address and length of the controller's registers.
16 - #pwm-cells: must be 2. See pwm.yaml in this directory for a description of
17   the cell format.
18 - clocks: phandle and clock specifier of the PWM reference clock.
19 - clock-names: must contain the following, except for MT7628 which
20                has no clocks
21   - "top": the top clock generator
22   - "main": clock used by the PWM core
23   - "pwm1-3": the three per PWM clocks for mt8365
24   - "pwm1-8": the eight per PWM clocks for mt2712
25   - "pwm1-6": the six per PWM clocks for mt7622
26   - "pwm1-5": the five per PWM clocks for mt7623
27   - "pwm1"  : the PWM1 clock for mt7629
28 - pinctrl-names: Must contain a "default" entry.
29 - pinctrl-0: One property must exist for each entry in pinctrl-names.
30   See pinctrl/pinctrl-bindings.txt for details of the property values.
31
32Optional properties:
33- assigned-clocks: Reference to the PWM clock entries.
34- assigned-clock-parents: The phandle of the parent clock of PWM clock.
