* ALSA SoC SPDIF DIR (Digital Interface Reciever) driver
|

*
|
||||
* Based on ALSA SoC SPDIF DIT driver
|
||||
*
|
||||
* This driver is used by controllers which can operate in DIR (SPDI/F) where
|
||||
* no codec is needed. This file provides stub codec that can be used
|
||||
* in these configurations. SPEAr SPDIF IN Audio controller uses this driver.
