The Linux Common Display Framework was started by Laurent Pinchart as a way for sharing transmitter and bridge devices between different subsystems, such as DRM and V4L2 or even FBDEV drivers. While the CDF work has been ongoing for months, it's received broad interest from a variety of different hardware vendors and stakeholders, particularly in the ARM Linux world.
On Friday was the third "request for comments" revision to the CDF patch-set, which is compromised of nineteen patches. These patches can be found on dri-devel.
Laurent Pinchart wrote, "this RFC isn't final. Given the high interest in CDF and the urgent tasks that kept delaying the next version of the patch set, I've decided to release v3 before completing all parts of the implementation." Hit up the aforelinked dri-devel patch-set for those Linux developers interested in more information on the Common Display Framework for the kernel.
