Hi all,

I've dropped the fun parts of this series since they need more work, but
figured drm_bridge_init() as a concept is still valuable on its own (and
I think I'll need it to roll out device links for registered bridges),
so here goes.

v2:
 - expanded commit messages and added some extra bridge-related
   documentation (Daniel)
 - dropped v1 patches 29 and 30: 29 needs more work, and 30 depends on
   it
 - added all remaining drm_bridge implementers, found by searching for
   drm_bridge_funcs which is mandatory for any bridge; new uses in
   patches 3, 27, and 28 (Sam)
 - due to the above, I've decided to squash all analogix changes into
   one patch

v1 [https://patchwork.freedesktop.org/series/70039/] cover text below:

This series adds device links support to drm_bridge. The motivation
behind it is that a drm_bridge in a module could get removed under the
feet of the bridge user without warning, so we need a way to remove and
reprobe the client as needed to avoid peering into the void.

1: Add a drm_bridge_init() function which wraps all initialisation of
the structure prior to calling drm_bridge_add().

2-26,28: Apply the drm_bridge_init() refactor to every bridge that uses
drm_bridge_add().

27: Minor cleanup in rcar-du.

29: Add of_drm_find_bridge_devlink() which functions the same as
of_drm_find_bridge() plus adds a device device link from the owning
drm_device to the bridge device.

30: As a motivating example, convert komeda to exclusively use
drm_bridge for its pipe outputs; this isn't a regression in usability
any more since device links bring the same automatic remove/reprobe
feature as components.
