Yes, I know fbdev is now in maintenance-only mode, reimplementing it
on top of DRM is on my roadmap, including rewriting a saner version
of the modesetting code. The current version is beyond repair. I'll
start working on it once I managed to purchase the hardware for testing.

But currently my objectively is to have something usable during the
transitional period. The major user of the chipset was Yeeloong 8089D
laptop - a choice for many non-x86 and MIPS hobbyists for experimentation.
Getting the current version of the patch merged would solve the immediate
usability issues, and then trying to get some platform drivers merged.
And after completing the preliminary upstreaming process, since then,
can start working on a DRM version of the driver, and possibly eventually
remove the fbdev version of sm712fb entirely. 

The 2D acceleration implementation is strictly no more than 200 lines,
the vast majority of the code insertions are comments and documentation
changes ranting about the known issues of the driver/hardware, nothing
non-trivial is added and I think the changeset is manageable and would
not be a burden for the fbdev maintainers, and I can grarantee that I will
not add any other new features to this driver.

Cheers,
