Release 4.11 sound/soc/codecs/spdif_transmitter.c
/*
* ALSA SoC SPDIF DIT driver
*
* This driver is used by controllers which can operate in DIT (SPDI/F) where
* no codec is needed. This file provides stub codec that can be used
* in these configurations. TI DaVinci Audio controller uses this driver.
