drm/bridge: ssd2825: don't create a panel_bridge

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

Now a panel_bridge is automatically created for every drm_panel and the
panel-bridge API is just a deprecated wrapper to access it.

Update and simplify the code by just getting a reference to the
already-existing bridge using of_drm_get_bridge_by_endpoint().

As of_drm_get_bridge_by_endpoint() returns a refcounted bridge, take care
of putting the bridge reference when not used anymore.

Update and simplify the code by just getting a reference to the

And since of_drm_find_and_get_bridge() returns a refcounted bridge, take
care of putting the bridge reference by using bridge->next_bridge.

drm: of: move drm_of_find_panel_or_bridge() from drm_of.c to drm_panel.c

2026-09-28T07:04:48+00:00

We want to move drm_panel.o from the main drm module to a new drm_panel
module, but there is one function in the drm module that calls into
drm_panel.c code:

  drm_of_find_panel_or_bridge() (drm_of.c, drm module)
     -> calls of_drm_find_panel (drm_panel.c, future drm_panel module)

Avoid this issue by moving drm_of_find_panel_or_bridge() to drm_panel.c.

Update Kconfig symbols of drivers calling drm_of_find_panel_or_bridge() to
select DRM_PANEL when this is not done already.

No functional changes, just moving code around.

2026-09-28T05:35:57+00:00

This driver uses drm_panel_bridge_add_typed() and
drm_panel_bridge_remove(), which are enabled by DRM_PANEL_BRIDGE.

Leave the 'select DRM_PANEL' because it is needed for drm_panel_put() and
drm_panel_enable() which the driver uses.
