Cover letter [PATCH RFC 0/3] drm/bridge: adjust bridge module's refcount and more
Note! This series is not yet ready and should not be used as is, it is just an RFC.
The function documentation is missing and so are the modifications to all affected drivers. I have added the modification patches for tilcdc and ti-tfp410 to serve as an example and I have put them into separate patches for readability.
For the matter of adding devres version of of_drm_get_bridge() and drm_bridge_alloc(), I think that is a good idea. With reference counting, each user can hold on to their reference to the bridge object as long as they need it. The bridge object exists as long as any of the users still holds on to it.
Cheers,
Jyri
