[PATCH 2/2] ASoC: aic: Support for AIC family DSPs
From: Mehar Bajwa
Date: Tue Dec 11 2012 - 08:40:15 EST
AIC family of audio CODECs from TI features a programmable miniDSP for
performing signal processing operations. Due to commonality of functions
across the CODECs a common library will be used to provide support for them.
