From b60be4aa40cff1ebfffc09f92b9007ac1fa24fb4 Mon Sep 17 00:00:00 2001 From: Padmavathi Venna Date: Fri, 26 Jul 2013 19:06:48 +0530 Subject: ASoC: Samsung: I2S: Modify driver to give more flexibility This patch modifies the i2s driver to give flexibility towards register handling. This is a pre requirement for enabling i2s support on Exynos5420. This patch modifies only the required registers as a pre-requirement to support on Exynos5420.
