Samsung has different versions of I2S introduced in different platforms. Each version has some new support added for multichannel, secondary fifo, s/w reset control, internal mux for rclk src clk and tdm support. Each newly added change has a quirk. So this patch adds all the required quirks as driver data and based on compatible string from dtsi fetches the quirks. This also adds i2s support on exynos5420 and make relevent changes in the dtsi files. Changes since V1: - Pass quirks as driver data and fetch the quirks based on compatible string from dtsi file as suggested by Tomasz Figa and Mark Brown - Make the I2S driver more flexible with respect to register access as suggested by Tomasz Figa and Mark Brown - Add 5420 support in the driver. - Modify the dtsi files with the corresponding compatible strings and removed the i2s quirks from 5250 dtsi file. - Updated the i2s Documentation with relevent changes and i2s versioning info. - Add i2s nodes on exynos5420.dtsi - Enable sound support on smdk5420 This patch set is dependent on the following dma and audio subsystem clk controller patches. http://comments.gmane.org/gmane.linux.kernel.samsung-soc/20661 http://comments.gmane.org/gmane.linux.kernel.samsung-soc/20668 This patch set is made based on Kukjin Kim for-next branch.
