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. [1] https://lwn.net/Articles/783127/ Any inputs? Jagan.
