drm/bridge: panel: move all code to drm_panel.c

2026-09-28T07:40:09+00:00

Work is in progress for every drm_panel to embed a drm_bridge, replacing
the panel_bridge entirely. However most of the panel_bridge code will be
reused for the drm_bridge embedded into the drm_panel, so just move the
code there.

Adapt users of the moved functions to include drm_panel.h when necessary.

No functional changes, just moving code around.

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of  by the more specific
 where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.
