Hi Philipp,
I have added the mailing list to the reply because my answer could be
relevant for others as well.

It seems as if we have DDK 1.17 compiling fine and working at least on
omap3 me on DM3730), omap4 (Tony on Droid) and omap5 (me on Pyra Handheld).

On my BeagleBone it does not work, maybe something seems to be broken with
the different lcdc. I can load the pvrsrvm and start pvrsrvctl but then only
get "failed to set mode: Invalid argument" or
"drmModeGetResources failed: Operation not supported"

Otherwise, I can compile for jz4780 (mips) and load on the CI20 board. What I
want to experiment with is to run pvrsrvctl by qemu-arm-static and see what
happens but I have not yet installed the required arm libs. And there is no
working HDMI driver for that board.

Jonathan has made the omap driver work on the s5pc110 Samsung SoC. So we have
achieved broadening the number of platforms supported by a single driver tree
and the A83 is very welcome to join them.

Most likely the best approach is to look into how Jonathan did add the Samsung
chip to the DDK 1.17 version.

Then, I have restarted to push the DTS fixes for omap upstream.

It is not yet pushed to the repo and I plan to do it with v5.7-rc1, but we have
it in our Letux tree:

Finally I think to remember you have admin rights for the github group and there
had been requests to add users / enable wiki access:
