Adds device-tree bindings from SDMA on OMAP2+ devices. DMA client bindings are also added for devices that have SPI and MMC bindings populated. Client binding data is based upon existing HWMOD data for OMAP and has been checked against OMAP documentation. Please note that the underlying (legacy) OMAP SDMA driver has not been ported over to DT and this still needs to be done. However, this allows DMA clients to look-up the DMA resource information via device-tree. Testing includes ... 1. Boot tested on OMAP3430 SDP board and OMAP4430 SDP board with without device-tree present. 2. Testing of MMC1 with SD card on OMAP3430 SDP board and OMAP4430 SDP board with and without device-tree present. Testing branch available here [1]. Series is based upon v3.8 on top of the following ... - Vinod's topic/dmaengine_dt branch [3] - Matt Porter's series "DMA Engine support for AM33XX" [4] - Matt Porter's series "omap_hsmmc DT DMA Client support" [5] - Sourav Poddar's series "add omap mcspi device tree data" [6] V3 changes: - Updated name of of_dma_filter_info and statically initialised filter_fn member of this structure per Arnd's feedback. V2 changes: - Updated to Tony's omap-for-v3.9/multiplatform-v2 branch to pull in DMA changes for v3.9 - Added comma to omap_dma_driver structure as pointed out by Arnd. - Updated OMAP SDMA DT binding compatible strings to indicate which devices are bit compatible with each other with respect to the SDMA controller. Grant had mentioned in the past that he wants the compatible string to be based upon a particular device and not something generic like "ti,omap-sdma".
