From 6df703aefc81252447c69d24d2863007de2338e9 Mon Sep 17 00:00:00 2001 From: Herton Ronaldo Krzesinski Date: Wed, 4 Feb 2009 11:34:22 -0500 Subject: ALSA: hda - Dynamic detection of dmics/dmuxes/smuxes in stac92hd71bxx Detect the number of connected ports and number of smuxes dynamically, looking at pin configs, using new introduced functions stac92hd71bxx_connected_ports and stac92hd71bxx_connected_smuxes. Also use proper input mux configuration for 4port and 5port models.
