Subject: [PATCH v2 1/8] drm/i915: debugfs: HDCP2.2 capability read
Date: Sat,  9 Mar 2019 09:34:45 +0530	[thread overview]
Message-ID: <20190309040452.23699-2-ramalingam.c@intel.com> (raw)
In-Reply-To: <20190309040452.23699-1-ramalingam.c@intel.com>

Adding the HDCP2.2 capability of HDCP src and sink info into debugfs
entry "i915_hdcp_sink_capability"

This helps the userspace tests to skip the HDCP2.2 test on non HDCP2.2
sinks.
