From 2159ad936b7e7a8b26c99cf5b4476cfbb8c13e22 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 11 Oct 2012 11:54:02 +0900 Subject: ASoC: adsp: Add ADSP base support Many current Wolfson devices feature DSPs based around an architecture known as ADSP. Since there is a lot of commonality in the system integration of these devices a common library will be used to provide support for them. This version provides equivalent support for ADSP1 to that currently included in the WM2200 driver.
