OK. Just wondering how configuring tiler and changing the
rotation fits into all this.

OK. Well the pvr-omap4 testing-v5.4 has nasty ioctl proxying
dependencies to patching also omapdrm just to get it to
compile. AFAIK these hacks can never be merged to mainline
Linux, and will probably be a constant maintenance hassle.

Probably best to keep them out, or at least wait until I
have things working with the command translation so we
have a better idea what should be done with them.

Yeah I think we need to be able to emulate whatever version
to the userspace blobs.
