Hello Xinlei,

even though repeating these items may not give you errors, this is not really
the best way to do this.
I've done something similar here:
https://lore.kernel.org/linux-arm-kernel/20220217095242.13761-1-angelogioacchino.delregno@collabora.com/

So, for the compatibles needing mediatek,mt8183-disp-pwm it should be looking
similar to this:

- items:
     - enum:
         - mediatek,mt8186-disp-pwm
         - mediatek,mt8192-disp-pwm
         - mediatek,mt8195-disp-pwm
     - const: mediatek,mt8183-disp-pwm

Regards,
Angelo

Combine to 1 entry:

enum:
  - mediatek,mt8186-disp-pwm
