From 1023dbd90c1e3e87921198939917c1f50b4b6af7 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 11 Jan 2013 22:58:28 +0000 Subject: [PATCH] ASoC: wm_adsp: Add basic firmware selection support There are many firmwares available for ADSP devices. Add basic support for selecting between them, including a couple of feature sets in the set of available firmware to start off with.
