This patch series adds HDMI output to the jz4780/CI20 board. It is based on taking the old 3.18 vendor kernel and trying to achieve the same with modern DTS setup and new/modified drivers. Unfortunately, in this first RFC, only EDID and creation of /dev/fb0 are working. Also, HDMI hot plugging is detected. But there is no HDMI output signal. So some tiny piece seems to be missing to enable/configure the Synposys HDMI controller. We need help from the community to fix this. Note: device tree bindings are from 2015 and still seem to fit - except they are not in yaml format.
