Subject[RFC 0/8] MIPS: CI20: add HDMI out support
Date
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.

Original authors of most patches are
* Paul Boddie <paul@boddie.org.uk>
* Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com>
