From 4ca0c0d4784fa82d68733f7793e3487023e12282 Mon Sep 17 00:00:00 2001 From: Padmavathi Venna Date: Mon, 12 Aug 2013 15:19:52 +0530 Subject: ASoC: Samsung: I2S: Modify the I2S driver to support I2S on Exynos5420 Exynos5420 added support for I2S TDM mode. For this, there are some register changes in the I2S controller. This patch adds the relevant register changes to support I2S in normal mode. This patch adds a quirk for TDM mode and if TDM mode is present all the relevent changes will be applied.
