From 5b8cf7c773f0b2a48e7d546acd5edf054e51d286 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 1 Nov 2011 13:53:37 +0000 Subject: [PATCH] ASoC: Ensure the WM8962 oscillator and PLLs start up disabled commit 2af8de8c39cf58e5a5e40a9d5d71332da98e6ba7 upstream. Since there is no current software control for these they would otherwise be left enabled, consuming power.
