From: Ville Syrjälä <ville.syrj...@linux.intel.com> Add an optional secondary encoder state compute hook. This gets called after the normak .compute_config() has been called for all the encoders in the state. Thus in the new hook we can rely on all derived state populated by .compute_config() to be already set up. Should be useful for MST and port sync master/slave transcoder selection.
