The plan for the driver was to wait for the common di= splay=20 framework (CDF) and convert it to use CDF and then submit it upstream. = The=20 CDF has been rejected though. Meanwhile the V4L2 adv7511 driver has bee= n=20 merged. So now we are in the ugly situation that we have two different=20 drivers for two different frameworks. To fix this we need to merge thes= e two=20 drivers while still exposing the interfaces to both frameworks. > AXI SPDIF I found in 3.16, as you noticed; what about AXI HDMI?

We need to teach the DMAengine framework about cyclic interleaved trans= fers=20 before the AXI HDMI driver can be submitted upstream. - Lars
