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.
