Subject: [Intel-gfx] [PATCH 4/4] drm/i915: Add HDCP2.2 capable debug print
Date: Tue, 28 Jan 2020 19:24:25 +0530	[thread overview]
Message-ID: <20200128135425.14596-5-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20200128135425.14596-1-anshuman.gupta@intel.com>

Few CI panel claims to support HDCP 2.2 but at CI
HDCP IGT test execution these panels are not detecting
as HDCP 2.2 supported panels. Adding HDCP 2.2 version
print will be useful in such cases.
