From b43105dee8480ca5784de5c858d1cccee74ebfb1 Mon Sep 17 00:00:00 2001 From: Alban Bedel Date: Tue, 9 Apr 2013 17:13:59 +0200 Subject: ASoC: wm8903: Fix the bypass to HP/LINEOUT when no DAC or ADC is running commit f1ca493b0b5e8f42d3b2dc8877860db2983f47b6 upstream. The Charge Pump needs the DSP clock to work properly, without it the bypass to HP/LINEOUT is not working properly. This requirement is not mentioned in the datasheet but has been confirmed by Mark Brown from Wolfson.
