[Intel-gfx] [PATCH 00/10] Haswell unclaimed register fixes and power well enabling

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

Hi

This series fixes a few of our current "unclaimed register" messages, then it
introduces the code to disable the power well when we're using eDP only, and
then it fixes a few more "unclaimed register" messages brought by the power down
code. In the last patches we remove the GEN7_ERR_INT checking from I915_WRITE
and move it to the interrupt code.

>From my tests, after this series I still only see 1 "unclaimed register" message
that seems to be caused by our driver. All the other messages (there are a lot
of messages that happen all together when booting) stop when we blacklist
snd_hda_intel and its friends. Still, the plan is to get rid of all the
remaining messages.

Cheers,
Paulo
