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. [Confirmed by Jassi that no existing machine drivers are affected -- broonie] Signed-off-by: Jassi Brar <jassi.brar@samsung.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
