drm/i915/bxt: add dsi transcoders
The BXT display connections have DSI transcoders A and C that can be muxed to any pipe, not unlike the eDP transcoder. Add the notion of DSI transcoders. The "normal" transcoders A, B and C are not used with BXT DSI, so care must be taken to avoid accessing those registers with DSI transcoders in the hardware state readout, modeset, and generally everywhere. v2: addressing comments by Ville: - rename the dsi get config function to hsw_get_dsi_transcoder_state - rebase onto the higher level split of pipe/transcoder functions - use more has_dsi_encoder as we can now because of the above, with no need to look at the transcoder so much - rename IS_DSI_TRANSCODER to transcoder_is_dsi - use the above a bit more instead of comparing to < TRANSCODER_EDP Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/299740536b7941e31b2744f3ce34f7afe936a771.1458313400.git.jani.nikula@intel.com
