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:
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?
