This series addresses the requriement of below HDCP compliance tests

One of the patch uses the I915 power infra-structure for checking
the power state of PW#1. Which enables the init path for all legacy
platforms.
And encoder specific msg availability detection is moved into hdcp_shim.
This will help to sync with DP hdcp data availability in the best
possible way by fielding the CP_IRQ.
Do we want any of these on 4.16 or backported?
Rodrigo,
The changes are for addressing the compliance gaps.
So IMHO at present there is no need for back porting them.
Please consider the use of "Fixes:" on whatever makes sense.
Sure thanks.

Thanks,
Rodrigo.
