Subject: [PATCH v6 02/10] drm/i915: debugfs: HDCP2.2 capability read
Date: Thu,  2 May 2019 18:52:55 +0530	[thread overview]
Message-ID: <20190502132303.27696-3-ramalingam.c@intel.com> (raw)
In-Reply-To: <20190502132303.27696-1-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.

v2:
  Rebased.
