Hi all,
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.
