[PATCH V6 00/10] Add DT support for i2s

[Padmavathi Venna]

This patch set is dependent on the following patches from
Vinod Koul next branch
1)of: Add generic device tree DMA helpers
2)dmaengine: add helper function to request a slave DMA channel

and also dependent on
1)DMA: PL330: Add xlate function
2)DMA: PL330: Register the DMA controller with the generic DMA helpers
3)ARM: dts: Add #dma-cells for generic dma binding support
4)DMA: PL330: Modify pl330 filter based on new generic dma dt bindings.

This patch set is made based Kukjin Kim for-next branch

Changes since V5:
	- Add generic DMA DT binding support
	- Change the compatible name as suggested by Grant,Mark and Kukjin
	- Make dma dev request api compatible to DT and non-DT
	- Fix compilation error in dmaengine.h for non-DT case 
	- Add basic device tree based lookup for smdk wm8994 machine file.
	- Make SPI driver use generic DMA DT bindings support

Changes since V4:
        - Add a new patch for renaming the samsung i2s secondary fifo interface
          device name from "samsung-i2s.4" to "samsung-i2s-sec"
        - Add platform_device_id table for the primary and secondary DAIs
        - Avoid using of alias ids in the i2s driver by adding of_device_id
          table. Primary device can get registered via dt or non-dt but secondary
          device can get registered only at runtime because the secondary is not
          physically present on the board.

Changes since V3:
        - Added syntex of gpio specifier as suggested by Mark Brown in
          DT document file
        - Added the requirement for having I2S alias ids
        - Explained about gpio lines
        - Made a seperate patch to get the I2S rclk src clk from alias ID

Changes since V2:
        - Rebased on 3.7-rc3
        - Custom DT bindings are prefixed with samsung
        - As generic device tree DMA helpers not yet mainlined
          I am still using custom dma bindings. So added a
          priliminary statement regarding the same. I will rework
          on my patch once generic DMA helpers are mainlined.

Chnages since V1:
        - Rebased on 3.6-rc6
