From 1b5d0160e8f17db0714016a2550d3b1d65c70c3e Mon Sep 17 00:00:00 2001 From: Bard Liao Date: Fri, 27 Mar 2015 20:19:08 +0800 Subject: [PATCH] ASoC: rt5645: Use update_bits for bit control 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.
