On gen12+ platforms, HDCP HW is associated to the transcoder. Hence on every modeset update associated transcoder into the intel_hdcp of the port. v2: s/trans/cpu_transcoder [Jani] v3: comment is added for fw_ddi init for gen12+ [Shashank] only hdcp capable transcoder is translated into fw_tc [Shashank] v4: fw_tc initialization is kept for modeset. [Tomas] few extra doc is added at port_data init [Tomas] v5: Few comments are improvised [Tomas] Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Shashank Sharma <shashank.sharma@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190828164216.405-6-ramalingam.c@intel.com
