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.

New bindings in DT Schema format please... We want to have then in a formal launguage so we can use these to verify the DT files.
