From 010ff262269c6ad84acba98eab2d7843919c7ccf Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 17 Aug 2009 17:39:22 +0100 Subject: ASoC: Add input and output AIF widgets Currently DAPM interfaces with the audio streams to and from the processor at the DAC and ADC widgets. As the digital capabilities of parts increases this is becoming a less and less able to meet the needs of parts. To meet the needs of these devices create new widgets interfacing with the TDM bus but not integrated into any other functionality. Audio can then be routed to and from these widgets using existing routing widgets. A slot number is provided in the definition but this is currently not used yet. This is intended to support devices which can use more than one TDM slot on a single interface.
