Stable was c/c on patch 3. I want to do more tests on patches 4-6, with both progressive video and RF. It would also be nice if someone could test it on OMAP3, to be sure that no regressions happened there. So, my goal is to send those patches for -rc2, assuming that we can do such tests, as it is likely too late for -rc1, as we'll have a short merge window this time.
