v5:
Remove ddr_edge_sel and use output_fmts to determine
which edge to be set.

v4:
Use output_fmts to determine whether it is dual edge.
Rebase to v5.13-rc1

v3:
Modify clock rate for dual edge setting.
Add more bridge function.

v2:
Modify unused code

v1:
DPI can sample on falling, rising or both edge.
When DPI sample the data both rising and falling edge.
It can reduce half data io pins.

Rex-BC Chen (3):
  [v5] drm/mediatek: dpi dual edge sample mode support
  [v5] drm/mediatek: config driver data to support dual edge sample
  [v5] drm/mediatek: dpi: add bus format negotiation
