From 51c6ab130642ed975681df843c772dda48a1d2ed Mon Sep 17 00:00:00 2001 From: Jassi Brar Date: Wed, 10 Mar 2010 16:48:51 +0900 Subject: ASoC: S3C: I2Sv2: Reject immidiate register value Towards generalizing CPU driver interface, do not accept direct field values for the BCLK and RCLK. The machine driver should simply request the FS-multiple and not provide the value to be set in divide field of IISMOD.
