[GIT PULL] OMAP DSS fixes for 3.3-rc

Hi Florian,

Two fixes for OMAP DSS for 3.3:

First one gets the HDMI output working again. Managing the clocks for
OMAP4 is not very simple, and this patch circumvents the problems we
have in the clock framework. It's a clean but rather hacky fix, but it
shouldn't cause any side-effects. The issue will hopefully be fixed
properly with DT when we'll get proper parent-child hierarchy for DSS HW
submodules.

The second one is a simple fix for HDMI hotplug detection, which I
missed when I wrote the HDMI PHY fix
(c49d005b6cc8491fad5b24f82805be2d6bcbd3dd).

Merged. You would add
Cc: stable@vger.kernel.org
to patches if appropriate?

Thanks. Yes, I have sent a separate mail to stable list, as the patches
needed some tuning to apply.

Tomi, sorry.
You have already sent a mail to stable@vger.kernel.org.
Good luck.

I agree on Florian's opinion.
It would be good to add this patch to stable kernel. :)

[GIT PULL] OMAP DSS fixes for 3.3-rc

[Tomi Valkeinen]

[-- Attachment #1: Type: text/plain, Size: 2031 bytes --]

Hi Florian,

Here are two major fixes for OMAP DSS driver.

The first (OMAPDSS: use sync versions...) fixes problem with system
suspend, which causes omapdss power management to give WARNs and
generally malfunction on system suspend/resume.

The second (the rest of the patches) implements a workaround for HW bug,
which causes physical damage to the board if the HDMI cable is
disconnected at a "wrong" time. The actual fix is in the last patch, but
the board files needed some cleanups and a new GPIO, which is what the
smaller patches do.

The branch is based on fbdev/fbdev-next. Is that ok?

 Tomi

Yes, that worked well, as I didn't start to collect 3.4 material there. Merged.
