[PATCH v3,0/6] Convert pwm-mtk-disp.txt to

[xinlei.lee]

From: Xinlei Lee <xinlei.lee@mediatek.com>

Changes since v2:
1. Modify the PWM name to DISP_PWM.
2. Include pwm.yaml.
3. Separate conversion files and add/remove operations.

Changes since v1:
1. Fixed formatting issues mentioned in the v1.
2. Delete pwm-mtk-disp.txt.
3. Add mtk_pwm dt_maintainers.
4. Add "#pwm-cells" & power-domains properties.
5. Make dt_checking successful.

Xinlei Lee (6):
  dt-bindings: pwm: Convert pwm-mtk-disp.txt to mediatek,pwm-disp.yaml
    format
  dt-bindings: pwm: Remove compatible for MediaTek MT8167
  dt-bindings: pwm: Add compatible for MediaTek MT8183
  dt-bindings: pwm: Add compatible for MediaTek MT8192

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
