In that thread there is a proposal for removing the old fbdev/mxsfb
driver entirely.

That would break old DTBs, isn't this generally considered bad? Also,
are we sure the removal of fbdev/mxsfb wouldn't lose any features?

What my series does is make both drivers work with the same kernel
image and turns the choice into a board-level dtb decision. Supporting
everything at once seems desirable to me and it allows for a very
smooth upgrade path.

The old driver could be removed later, after all users are converted.
