I work for TI and have since picked up the work on the v7 patch series
that Anand and others last worked on. I've been forward porting the
exisiting patches on top of the latest 'master' commit, doing some
further cleanup also considering v7 feedback, plus making enhancements
needed to better support TI K3 SoCs. I've also added AM62x support, and
currently working on adding GPU support for AM62x (I have it already
working being able to run Weston and Chocolate Doom for testing
purposes, just needs some more cleanup).

My intermediate work is posted here [1] together with some instructions
and how to get it to work for anybody interested in the full solution
*today*.

My plan is once GPU support is complete and cleaned up I'll post a v8
series to this mailing list here with everything in it, and work with
the community on any further cleanup that may be needed. I expect to be
able to start this process next week. So I'd appreciate if we can
refrain from posting additional TI K3 patches until then.

Once merged, the temporary page [1] will get updated and/or dismantled.
It is certainly not meant to be a "forked solution" of sorts, and was
only intended to be a stop-gap measure for some immediate customer needs
we had here at TI.

Thanks,
