Looks like you should take a look at the merge conflicts with
this one, maybe rebase it on 994c0e992522c123298b4a91b72f5e67ba2d1123.

Do you want this series for 3.2-rc or 3.3 at this point?

Seems that at least HDMI output is broken due to this series missing.

OK thanks, 3.2-rc it is.

The merge conflicts have been fixed, they were trivial.  Tomi, care to 
do a quick test boot with the updated branch

git://git.pwsan.com/linux-2.6 hwmod_dss_fixes_3.2rc

?

My testbed is down at the moment and won't have the chance to deal with it 
for a few more days.

Thanks, the patches in your branch look ok and work ok for me.

I suggest we only merge the ones with "fix" in the subject during the -rc
cycle. The others add new features for the reset, so they should wait until
v3.3 merge window.

Most of the other patches in the branch discuss what they fix in the patch 
descriptions, rather than the subject lines.  Do you want the subject 
lines rewritten to highlight this?

Well we should only merge major bugs and regressions during the -rc cycle.
It seems that at least "OMAP: HWMOD: Unify DSS resets for OMAPs" has high
flame potential based on that? Maybe we should wait until the next merge
window to start removing some of these workarounds?

I'm not sure what you mean...

The "Unify DSS resets..." patch itself fixes only a minor bug: "This
causes causes the HWMOD reset to fail for dss_dispc and dss_rfbi". But
it makes the next patch, "Ensure DSS works correctly...", possible. And
that patch fixes a bigger bug, DSS or the whole device hanging if the
bootloader had enabled the display (which I believe is the default on
the shipped beagles/pandas).

There's one patch in the series that is not a fix, though: "ARM: OMAP4:
HWMOD: remove extra clocks". I'm fine with queuing that for the next
merge window. But most of the patches have now somehow missed two merge
windows, and I'd really like to get them in.

OK let's try to get them in then. Hopefully after these DSS will be
more independent from the core omap changes.
