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.
Changes since V2: - Seperated out driver side changes and dts changes in two patch sets. - Replaced samsung,s3c6410-i2s-v4 with samsung,s3c6410-i2s-multi for more clarity as suggested by Tomasz Figa.
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 made based on Mark Brown for-next branch on sound.git.
