Subject: [PATCH 03/20] ASoC: S3C64XX: I2S: Make BCLK independent of sample size
Date: Wed, 10 Mar 2010 16:48:52 +0900	[thread overview]
Message-ID: <1268207349-9979-3-git-send-email-jassi.brar@samsung.com> (raw)
In-Reply-To: <1268207349-9979-2-git-send-email-jassi.brar@samsung.com>

For some CPU-CODEC and source clock combination we might need to set
BCLK to N*Sample_size*LRCLK, where N may be even 3 or 4, not just 2.

We can simply remove the dependency of BCLK on sample size as there
is already a callback(S3C_I2SV2_DIV_BCLK) available to set required BCLK.
