From b1a5fad5f8c063abfd9bd22f7de8de82927c7d54 Mon Sep 17 00:00:00 2001 From: Alexander Morozov Date: Tue, 27 Jan 2015 11:36:39 +0800 Subject: ASoC: wm8904: add dt ids table The WM8904 and WM8918 has the same data type, while the WM8912 has different data type. So, use the data in dt ids table to distinguish them.
