- * Default mode for SSP configuration is TDM 4 slot. One board/design,

- * second piggy-backed, output-only codec is inside the keyboard-dock
- * (which has extra speakers). Unlike the main rt5672 codec, we cannot
- * configure this codec, it is hard coded to use 2 channel 24 bit I2S.
- * Since we only support 2 channels anyways, there is no need for TDM
- * on any cht-bsw-rt5672 designs. So we simply use I2S 2ch everywhere.

+ * (or program both to yet another mode).
