Subject: [PATCH v3 0/9] drm/i915: Implement HDCP

Oh, hello there. Here's v3 of the HDCP patchset.

Highlights of v3 are:
- Add atomic_check/commit helpers to intel_hdcp to handle state transitions and
  call enable/disable at the right time.
- intel_hdcp_check_link() gets moved again to avoid being called with locks held
- Split out setting the property from the check worker into its own dedicated
  worker. This avoids deadlock when doing a synchronous cancel with mode_config
  lock(s) held.
- Add internal connector->hdcp_value to track actual state of hardware
- Add "indexed writes" to GMBUS driver
- Rebase on drm-tip to pick up new wait_for
- Tested with igt patch

Thanks!

Sean
