RFC V1 2020-02-26 20:13:06:
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.
