Fixes should always be kept. Reverting a fix is not an option.
Instead, do incremental patches on the top of it.

Sounds like a plan.

Firstly, the RFC series should be converted into something that can
be applicable upstream, e. g.:

- doing the changes over the top of upstream, instead of needing to
  revert patches;

- change all drivers as the kAPI changes;

- be git bisectable, e. g. all patches should compile and run fine
  after each single patch, without introducing regressions.

That probably means that the series should be tested not only on
omap3, but also on some other device drivers.
