Subject: [PATCH 3/4] ASoC: rt5645: Use update_bits for bit control
Date: Fri, 27 Mar 2015 20:19:08 +0800	[thread overview]
Message-ID: <1427458749-821-3-git-send-email-bardliao@realtek.com> (raw)
In-Reply-To: <1427458749-821-1-git-send-email-bardliao@realtek.com>

In codec bias level off, we need to disable gate mode with MCLK
for power saving. It is set by one bit. We don't need to write
while register for that.
