Public bug reported:
We've been asked by Intel to backport the following patches to enable "Haswell
ULT with Lynx point core".
It's been tested and confirmed working by Intel under the 3.8 kernel.
I think it makes sense to backport them to the 3.5 kernel too.
1. commit 7b9f35a6dd72f89452c58bbdbaf063027bf857ec
Author: Wang Xingchao <xingchao.w...@intel.com>
Date: Tue Jan 22 23:25:25 2013 +0800
drm/i915: HDMI/DP - ELD info refresh support for Haswell
* The above is in the 3.9-rc1 kernel. I lack the driver knowledge to do
a proper review.
2. commit 4a7c516bf0cd697dbbee11db6258e3b3146e41a6
Author: Wang Xingchao <xingchao.w...@linux.intel.com>
Date: Fri Feb 1 22:42:19 2013 +0800
ALSA - HDA: New PCI ID for Haswell ULT
* The above is in the 3.9-rc1 kernel. Very low regression risk (just
adds another ID). Can be cherry-picked as is for 3.8, needs backport for
3.5.
3.commit a15d05db41b1d5c9f2c3af11dfbfd46818cc64ba
Author: Mengdong Lin <mengdong....@intel.com>

ALSA: hda - Support rereading widgets under the function group
* The above is in the 3.9-rc1 kernel. Adds new code that isn't used by
anything (except the patch below), so can just be added.
4. commit 1611a9c931e95fab871a33beba49cc9ea39bbba8
Author: Mengdong Lin <mengdong....@intel.com>
Date: Fri Feb 8 17:09:52 2013 -0500
ALSA: hda - Add fixup for Haswell to enable all pin and convertor
widgets
* The above is in the 3.9-rc1 kernel. It seems very targeted towards a
specific board. I wonder how much sense it does to actually backport
this one. I'm asking Intel about it.
