Subject: [PATCH v4 09/16] drm/i915/hdcp: Encapsulate hdcp_port_data to dig_port
Date: Tue, 27 Oct 2020 22:12:01 +0530 [thread overview]
Message-ID: <20201027164208.10026-10-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20201027164208.10026-1-anshuman.gupta@intel.com>
hdcp_port_data is specific to a port on which HDCP
encryption is getting enabled, so encapsulate it to
intel_digital_port.
This will be required to enable HDCP 2.2 stream encryption.
