Subject: [PATCH 1/1] ASoC: sgtl5000: enable VAG_POWER for LINE_IN
Date: Fri, 27 Jul 2012 19:18:42 +0800 [thread overview]
Message-ID: <1343387922-25227-1-git-send-email-b29396@freescale.com> (raw)
From: Dong Aisheng <dong.aisheng@linaro.org>
LINE_IN also needs VAG_POWER on or we may hear noise when directly
route LINE_IN to Headphone Mux.
Tested on imx28evk.
