Well, there are some things missing:
* GPS
* Modem power enable through rfkill unblock wwan
* more audio functions like codecs and hardware voice routing

And some other not so big things, like the iio-input-bridge (map iio-accelerometer to /dev/input/event).
Some topics are known to be inacceptable (touch screen pre-calibration from device-tree).

If you need write access to update that page, please let me know.

Yes, it is the result of a big merge of all feature branches (also for other supported platforms) done by this script and mergefile:

http://git.goldelico.com/?p=letux-kernel.git;a=blob;f=Letux/scripts/merge;h=bccb7288eed521f716aaf5784af1282ac80cc6ab;hb=refs/heads/letux-4.20-rc7
http://git.goldelico.com/?p=letux-kernel.git;a=blob;f=Letux/scripts/mergefile;h=764a8d96ad481b9f8bd68aa4e79c4e9932da44c8;hb=refs/heads/letux-4.20-rc7

Basically we have a series like linux-next, i.e. linus/v4.20-rc* plus merge of all feature branches.

The GTA04-DT things mainly come from:
