From 2005bd881d273456e26a0b2027976f75fc47701f Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Wed, 16 Dec 2015 13:02:55 +0000 Subject: [PATCH] ASoC: wm8974: add devicetree support This adds devicetree support to the wm8974 codec driver. With a DT-based kernel, there is no board-specific setting to select the driver so allow it to be manually chosen.
