Subject: [PATCH v9 4/6] misc/mei/hdcp: Fill transcoder index in port info
Date: Thu, 22 Aug 2019 20:49:02 +0530	[thread overview]
Message-ID: <20190822151904.17919-5-ramalingam.c@intel.com> (raw)
In-Reply-To: <20190822151904.17919-1-ramalingam.c@intel.com>

For gen12+ platform we need to pass the transcoder info
as part of the port info into ME FW.

This change fills the payload for ME FW from hdcp_port_data.
