From 7aca69f9fe8f04ca37a01e2540960c53b24e3223 Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Mon, 9 Jan 2012 12:36:24 +0000 Subject: [PATCH] ASoC: utils - Add support for a dummy codec driver. This is useful to create dummy codec devices where we need to have some DAI links without a real Codec. e.g. could be used to represent dumb FM, MODEM, etc This is also used by dynamic PCM for DAI links that have no codec.
