[Letux-kernel] Status of JZ4780/CI20 upstream support

Linus has released v5.2 and I wonder about the status of
JZ4780/CI20 upstream support.

I can boot the CI20 V2a. SD card and Ethernet are working
and I could forward-port some patches from the old 3.18
kernel to make the LED0..LED3 gpio-leds work.

What is missing or not working on my setup:
* HDMI / DRM / framebuffer
* ov5640 camera
* WiFi
* (not tested) Audio
* Paul reported that only one core seems to be up and running

So I wonder who else is working on such things and how I (and
we from the LetuxOS kernel project [1]) can support.

Maybe there have been unsiccessful attempts to get the missing
features upstream and we would like to learn about.

My personal long-term goal is to get the PVR/SGX working again
and harmonize that with the code available for OMAP3/4/5 to
make it easier to work on a single source code version of the
kernel driver.

BR and thanks,
