From: Libin Yang <libin.yang@xxxxxxxxx>
This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit 2d846c74027231264e57e4e34faf9576394e3ce0 upstream.
HDMI/DP codec on SKL/BSW is in the power well.
The power well must be turned on before probing the
HDMI/DP codec.
This is a temporary patch, which will power on the
powerwell by adding AZX_DCAPS_I915_POWERWELL for SKL
and BSW. After restructuring and new flag is added,
this patch will be reverted.
