From 97d0a868450d08fae0db3f53459852901c6e2f4f Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Mon, 24 Jun 2013 16:31:32 +0200 Subject: ASoC: adau1701: add support for pin muxing The ADAU1701 has 12 pins that can be configured depending on the system configuration. Allow settting the corresponding registers from DT.
