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: 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. 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?
