I tested your branch and those patches work just fine on droid 4.

I did not test the fifo patch as it's missing something compiles
as loadable modules:

ERROR: "dispc_ovl_set_fifo_threshold" [drivers/gpu/drm/omapdrm/omapdrm.ko] undefined!
ERROR: "dispc_ovl_compute_fifo_thresholds" [drivers/gpu/drm/omapdrm/omapdrm.ko] undefined!

Probably just EXPORT_SYMBOL missing?

Anyways, yeah I guess that set is pretty much ready to be sent for
review if you feel like sending it. Or let me know if you want me to
send it.

Regards,

Tony
