     MediaTek PWM controller
     
     Required properties:
      - compatible: should be "mediatek,<name>-pwm":
        - "mediatek,mt2712-pwm": found on mt2712 SoC.
        - "mediatek,mt6795-pwm": found on mt6795 SoC.
        - "mediatek,mt7622-pwm": found on mt7622 SoC.
        - "mediatek,mt7623-pwm": found on mt7623 SoC.
        - "mediatek,mt7628-pwm": found on mt7628 SoC.
       - "mediatek,mt7629-pwm": found on mt7629 SoC.
       - "mediatek,mt8183-pwm": found on mt8183 SoC.
       - "mediatek,mt8195-pwm", "mediatek,mt8183-pwm": found on mt8195 SoC.
       - "mediatek,mt8365-pwm": found on mt8365 SoC.
       - "mediatek,mt8516-pwm": found on mt8516 SoC.
     - reg: physical base address and length of the controller's registers.
     - #pwm-cells: must be 2. See pwm.yaml in this directory for a description of
       the cell format.
     - clocks: phandle and clock specifier of the PWM reference clock.
     - clock-names: must contain the following, except for MT7628 which
                    has no clocks
       - "top": the top clock generator
       - "main": clock used by the PWM core
       - "pwm1-3": the three per PWM clocks for mt8365
       - "pwm1-8": the eight per PWM clocks for mt2712
       - "pwm1-6": the six per PWM clocks for mt7622
       - "pwm1-5": the five per PWM clocks for mt7623
       - "pwm1"  : the PWM1 clock for mt7629
     - pinctrl-names: Must contain a "default" entry.
     - pinctrl-0: One property must exist for each entry in pinctrl-names.
       See pinctrl/pinctrl-bindings.txt for details of the property values.
    
    Optional properties:
    - assigned-clocks: Reference to the PWM clock entries.
    - assigned-clock-parents: The phandle of the parent clock of PWM clock.
    
    Example:
            pwm0: pwm@11006000 {
                    compatible = "mediatek,mt7623-pwm";
                    reg = <0 0x11006000 0 0x1000>;
                    #pwm-cells = <2>;
                    clocks = <&topckgen CLK_TOP_PWM_SEL>,
                             <&pericfg CLK_PERI_PWM>,
                             <&pericfg CLK_PERI_PWM1>,
                             <&pericfg CLK_PERI_PWM2>,

                             <&pericfg CLK_PERI_PWM4>,
                             <&pericfg CLK_PERI_PWM5>;
                    clock-names = "top", "main", "pwm1", "pwm2",
                                  "pwm3", "pwm4", "pwm5";
                    pinctrl-names = "default";
                    pinctrl-0 = <&pwm0_pins>;
            };
