From: Sean Paul seanpaul@chromium.org
No functional changes, this set has the following changes since v6: - rebased on drm-tip - split "drm/i915: Clean up intel_hdcp_disable" out of "drm/i915: Don't fully disable HDCP on a port if multiple pipes are using it" - remove hdcp2 dpmst stubs
Regarding "level of testing" questions, I've tested with multiple MST hubs and displays. I don't have any compliance gear so all of this is desk tested and works for me.
