[PATCH v5,0/4] Convert pwm-mtk-disp.txt to mediatek, pwm-disp.yaml format

[xinlei.lee]

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

Changes since v4:
1.Base on Linux-next.
2.Cancel removal of mt8167 compatiable patch.

Changes since v3:
1. Combine multiplexed socs into one entry

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 (4):
  dt-bindings: pwm: Convert pwm-mtk-disp.txt to mediatek,pwm-disp.yaml
    format
  dt-bindings: pwm: Add compatible for MediaTek MT8192
  dt-bindings: pwm: Add compatible for MediaTek MT8195
  dt-bindings: pwm: Add compatible for MediaTek MT8186
