You are probably right!

I think I should have been more persistent when asking on how to deal
with these patches. Typically they should all have gone together via
one tree, or we needed a slower way forward keeping changes more
standalone.

Anyway, according to kernelci.org, which builds and boot my next
branch omap3/4 seems to boot now...
