Greg,
Please incorporate the latest imx-drm non-urgent fixes, which can be found at:
git://ftp.arm.linux.org.uk/~rmk/linux-arm.git imx-drm-fixes
with SHA1 1e6d486be4ea3f17c99c933703f53a6d566292a9.
These are the less urgent fixes, but nevertheless, I think they should
be submitted for an -rc kernel at some point during this cycle.
The change from Denis gets rid of some confusion about clock polarities,
and aligns the code with u-boot's code. This is more a cleanup than a
fix, but it is low impact as a grep reveals that both sites that use this
variable are fixed appropriately.
The remainder from Philipp resolve a bug in the driver where the hardware
stops providing video data after a number of modesets, and requires the
SoC to be reset to recover. This required some reorganisation of the code,
which is why the change is soo large and has been split across multiple
patches.
I've been running this with imx-hdmi locally for a number of weeks and
have seen nothing detrimental.
This will update the following files:
