ASoC: hdac_hdmi: Add machine pin widget for each port
Represent each port as machine DAPM pin widget. This helps in enable/disable pin when monitor is connected/disconnected in case pcm is rendered to multiple ports. Create machine pin widgets and pin switch kcontrol for each port and report based on the pin status Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Acked-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
