Create a remote HDCP capability shim function which can read the remote monitor HDCP capability when in MST configuration. --v2 -Add an assertion to make sure only mst encoder call this remote_cap function [Ankit] --v3 -rename remote_hdcp_cap to remote_hdcp_capability [Jani] --v4 -fix hdcp2_prerequisite check condition -Move intel_dp_hdcp_get_remote_capability to dp_mst shim instead of having it in dp shim [Ankit] Signed-off-by: Suraj Kandpal <suraj.kandpal@intel.com> Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Signed-off-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240226051017.1652970-2-suraj.kandpal@intel.com
