-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_PWM3>,
- <&pericfg CLK_PERI_PWM4>,
- <&pericfg CLK_PERI_PWM5>;
- clock-names = "top", "main", "pwm1", "pwm2",
- "pwm3", "pwm4", "pwm5";
- pinctrl-names = "default";
- pinctrl-0 = <&pwm0_pins>;
- };
