Subject: [PATCH v2 36/42] drm/i915: hdcp_check_link only on CP_IRQ
Date: Thu, 8 Mar 2018 17:29:03 +0530 [thread overview]
Message-ID: <1520510349-8385-37-git-send-email-ramalingam.c@intel.com> (raw)
In-Reply-To: <1520510349-8385-1-git-send-email-ramalingam.c@intel.com>
HDCP check link is invoked only on CP_IRQ detection, instead of all
short pulses.
