| Subject: ASoC: Ensure the WM8962 oscillator and PLLs start up disabled |
| |
| From: Mark Brown <broonie@opensource.wolfsonmicro.com> |
| |
| commit 2af8de8c39cf58e5a5e40a9d5d71332da98e6ba7 upstream. |
| |
| Since there is no current software control for these they would otherwise |
| be left enabled, consuming power. |
