+description: |
+  The audio support on the board is using pcm3168a codec connected to McASP10
+  serializers in parallel setup.
+  The pcm3168a SCKI clock is sourced from j721e AUDIO_REFCLK2 pin.
+  In order to support 48KHz and 44.1KHz family of sampling rates the parent
+  clock for AUDIO_REFCLK2 needs to be changed between PLL4 (for 48KHz) and
+  PLL15 (for 44.1KHz). The same PLLs are used for McASP10's AUXCLK clock via
+  different HSDIVIDER.

+description: |
+  The Infotainment board plugs into the Common Processor Board, the support of the
+  extension board is extending the CPB audio support, decribed in:
+  sound/ti,j721e-cpb-audio.txt
+
+  The audio support on the Infotainment Expansion Board consists of McASP0
+  connected to two pcm3168a codecs with dedicated set of serializers to each.
+  The SCKI for pcm3168a is sourced from j721e AUDIO_REFCLK0 pin.
+
+  In order to support 48KHz and 44.1KHz family of sampling rates the parent clock
+  for AUDIO_REFCLK0 needs to be changed between PLL4 (for 48KHz) and PLL15 (for
+  44.1KHz). The same PLLs are used for McASP0's AUXCLK clock via different
+  HSDIVIDER.
+
+  Note: the same PLL4 and PLL15 is used by the audio support on the CPB!
