[RFC PATCH 0/6] drm/i915: Implement HDCP

[Sean Paul]

Here's the RFC for my i915 HDCP patchset. The UABI is based on what we've been
using in Chrome for the past 3 years. I posted the property to the list back
then, but never had a mainline driver to implement it. I do now :-)

Things are mostly in place, danvet gave me some feedback that I will
incorporate in v1. However, in the interest of gaining more early feedback, I'm
posting this now.

TODO:
- Add kerneldoc for property
- Fix '//' comments
- Change to MIT license
- Rebase on Ville's gmbus fixes (thanks Ville)
- Improve documentation on drm_intel_hdcp_shim
- Fix async commit locking (ie: don't use connection_mutex)
- Don't change connector->state in enable, defer to worker
- Add igt coverage for the feature.

Thanks!

Sean
