Patch series to convert DMA library into platform driver using platform device model and adapting hwmod for omap2+. The original patch series : http://comments.gmane.org/gmane.linux.ports.arm.omap/46953 has been split into two patch series based on suggestion from Tony. (https://patchwork.kernel.org/patch/375831/) The first series will prepare existing DMA library for DMA hwmod and converting the same into platform driver. The second series will have: arch/arm/mach-omap1/dma.c omap1 specific platform init arch/arm/mach-omap2/dma.c omap2+ specific platform init drivers/dma/omap-dma.c driver using dmaengine.c Patch series1 Design: 1. The low level read/write macros are converted into static inline functions so that, these functions can be moved to respective mach-omap driver files later. (Thanks to Tony and Kevin for their suggestions on handling all omap register offset without adding extra enums) 2. Implements generic errata handling for all OMAP DMA errata. 3. DMA hwmod data is updated for respective hwmod db files. 4. The DMA library is split into two layers. a. The generic code is retained in plat-omap/dma.c b. The machine specific init code is moved to respective mach-omap dma files. Minimal machine specific code is moved to respective mach-omap dma files with this series. Rest of code movement and API cleanup's are handled in second series.
