[PATCH 3/3] ASoC: twl4030: enable routing audio to 'voice' interface.
From: NeilBrown <hidden>
Date: 2014-11-08 00:39:12

When 'voice' is some external connection, we power up the downlink when the downline amplifier is not muted, and power up the uplink when a new switch "Voice Uplink" is turned on.
