From 48e028eccabc9c246bfad175262582a1ce34a316 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 21 Feb 2011 17:11:59 -0800 Subject: ASoC: Support configuration of WM8958 microphone bias analogue parameters The WM8958 has a different microphone bias architecture to WM8994 so needs different configuration to WM8994. Support this in platform data.
