Subject: [PATCH v3 0/7] drm: sun4i: dsi: Convert drm bridge
Date: Mon, 15 Feb 2021 01:10:55 +0530 [thread overview]
Message-ID: <20210214194102.126146-1-jagan@amarulasolutions.com> (raw)
This series convert Allwinner DSI controller to full functional
drm bridge driver for supporting slave panel, bridges.
Here, are the previous version changes[1].
The key concern about these changes is about kms hotplug which
indeed not compatible with bridge conversion. However, I did
try several ways to support hotplug with the bridge but it's
resulting in a deadlock where bind never attach bridge until
bridge pointer found and bridge pointer cannot found until bind
finishes. Any inputs on this would be appreciated.

Any inputs?
Jagan.
