Hi, I haven't seen these merged nor any comment for these. Perhaps stable@kernel.org was wrong address, so adding stable@vger.kernel.org too.
Yes, stable@kernel.org has been "dead" since last October.
I have added one additional fix into for-3.2-stable branch, which fixes a problem with panel detection that the GPIO changes brought.
Sorry, but I don't accept pull requests. I need patches in email form, as described in the file, Documentation/stable_kernel_rules.txt. Please feel free to send them from your git tree that way.

Hi, There is a hardware bug on OMAP4, which may cause the HDMI output to break irreversibly. A work-around for the bug has been merged into mainline, but is missing from stable. I've backported the necessary patches on top of 3.0, 3.1 and 3.2 stable trees, and pushed the following branches to:
3.1 is long dead, so I can't do anything with those patches, sorry.

git://gitorious.org/linux-omap-dss2/linux.git fixes/for-3.0-stable fixes/for-3.1-stable fixes/for-3.2-stable 3.0 and 3.1 branches additionally contain a patch "OMAP: DSS2: HDMI: use default dividers", which fixes a problem with the HDMI clock divider. Without that the HDMI output won't start at all on those versions. The branches contain the following backported patches: OMAP: DSS2: HDMI: use default dividers OMAP: 4430SDP/Panda: use gpio_free_array to free HDMI gpios OMAP: 4430SDP/Panda: rename HPD GPIO to CT_CP_HPD OMAPDSS: remove wrong HDMI HPD muxing OMAP: 4430SDP/Panda: setup HDMI GPIO muxes OMAP: 4430SDP/Panda: add HDMI HPD gpio OMAPDSS: HDMI: PHY burnout fix Of those, the actual fix is in the last one, but as the GPIOs for HDMI were a mess, they needed some cleanup patches before the fix could be made.
That seems like a lot of backporting for a single fix, but I'll be glad to review them when you send them.

I'm not familiar with the process with stable kernels, so are the branches above fine to get them merged? Or should I send the patches with git-send-email?
Again, please read Documentation/stable_kernel_rules.txt, it explains how this all works. thanks, greg k-h
