Subject: [RFC v1 10/20] drm/hdcp: Handler for connector state change
Date: Wed, 12 Jul 2017 13:58:54 +0530	[thread overview]
Message-ID: <1499848144-8456-11-git-send-email-ramalingam.c@intel.com> (raw)
In-Reply-To: <1499848144-8456-1-git-send-email-ramalingam.c@intel.com>

On hotplug/detection of connector Panel's HDCP capability is probed.
On hot unplug of connector HDCP is diabled, if it has beed enabled.
