From 213eb0fb1e8e4ddfb8ffdb239c45ba2a1eef3dc2 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 21 Sep 2011 20:54:47 +0100 Subject: ASoC: Add platform data for WM1250 EV1 GPIOs The WM1250 EV1 has some GPIOs which can be used to control the behaviour at runtime. Request them all if supplied and add a set_bias_level() function to start and stop the clocks.
