From 3117bb3109dc223e186302f5dc8ce9ed04adca90 Mon Sep 17 00:00:00 2001 From: Nicolin Chen Date: Tue, 29 Jul 2014 18:08:53 +0800 Subject: ASoC: fsl_asrc: Add ASRC ASoC CPU DAI and platform drivers The Asynchronous Sample Rate Converter (ASRC) converts the sampling rate of a signal associated with an input clock into a signal associated with a different output clock. The driver currently works as a Front End of DPCM with other Back Ends DAI links such as ESAI<->CS42888 and SSI<->WM8962 and SAI. It converts the original sample rate to a common rate supported by Back Ends for playback while converts the common rate of Back Ends to a desired rate for capture. It has 3 pairs to support three different substreams within totally 10 channels.
