|
|
Required properties:
|
|
- compatible: should be "mediatek,<name>-disp-pwm":
|
|
- "mediatek,mt2701-disp-pwm": found on mt2701 SoC.
|
|
- "mediatek,mt6595-disp-pwm": found on mt6595 SoC.
|
|
- "mediatek,mt8167-disp-pwm", "mediatek,mt8173-disp-pwm": found on mt8167 SoC.
|
|
- "mediatek,mt8173-disp-pwm": found on mt8173 SoC.
|
|
- "mediatek,mt8183-disp-pwm": found on mt8183 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:
|
|
- "main": clock used to generate PWM signals.
|
|
- "mm": sync signals from the modules of mmsys.
|
|
- 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.
