Subject: [PATCH 2/2] ASoC: wm8961 - clear WM8961_MCLKDIV bit for freq <= 16500000
Date: Wed, 24 Nov 2010 10:21:54 +0800	[thread overview]
Message-ID: <1290565314.5506.4.camel@mola> (raw)
In-Reply-To: <1290565233.5506.2.camel@mola>

MCLKDIV bit of Register 04h Clocking1:
	0 : Divide by 1
	1 : Divide by 2

Thus in the case of freq <= 16500000, we should clear MCLKDIV bit.
