This series is based on mediatek-drm-next branch of
kernel/git/chunkuang.hu/linux.git

Changes in v12:
- Rebase on mediatek-drm-next branch of kernel/git/chunkuang.hu/linux.git

Changes in v11:
- Change "mtk-padding" to "mtk-disp-padding" for consistency
- Remove patch "drm/mediatek: Remove ineffectual power management codes
  for backward compatibility

Changes in v10:
- Remove "Reviewed-by" tags from the following commits:
    - drm/mediatek: Power on/off devices with function pointers
    - drm/mediatek: Manage component's clock with function pointers
- Separate the commit into smaller ones
    - (new) drm/mediatek: Remove ineffectual power management codes

Changes in v9:
- Add a static inline function to power off the device
- Change driver name to "mediatek-disp-padding"
- Fix typo and kernel doc format error

Changes in v8:
- Power on/off the components with .power_on() and .power_off()
- Remove mtk_padding_config()
- Remove "Reviewed-by" tags from "drm/mediatek: Add Padding to OVL adaptor"

Changes in v7:
- Start/Stop the components in OVL Adaptor with function pointers
- Refine Padding driver
- Fix underrun when the layer is switching off

Changes in v6:
- Separate the commits into smaller ones
- Add DPI input mode setting
- Fix VDOSYS1 power-on issues

Changes in v5:
- Reuse .clk_enable/.clk_disable in struct mtk_ddp_comp_funcs
  in mtk_disp_ovl_adaptor.c
- Adjust commits order

Changes in v4:
- Add new functions in mtk_disp_ovl_adaptor.c to enable/disable
  components and reuse them when clock enable/disable
- Rename components in mtk_disp_ovl_adaptor.c and sort them in
  alphabetical order

Changes in v3:
- Define macro MMSYS_RST_NR in mtk-mmsys.h and update reset table
- Fix typos (ETDHR -> ETHDR, VSNYC -> VSYNC)
- Rebase dt-bindings on linux-next
- Refine description of Padding
- Squash reset bit map commits for VDO0 and VDO1 into one

Changes in v2:
- Remove redundant compatibles of MT8188 because it shares the same
  configuration with MT8195
- Separate dt-bindings by modules
- Support reset bit mapping in mmsys driver
