The following patch series moves code to setup the DMA hardware and service interrupts from the hardware to the DMA engine driver. This reduces the dependency on the legacy DMA implementation. This series does not remove the channel allocation/freeing hooks which are used to manage the allocation of physical channels - this is the next step in the evolution. The patches which move the interrupt handling are currently less than perfect since they're writing to ENABLE_L0 under a different spinlock, and hence RFC only at the moment. arch/arm/mach-omap1/dma.c | 183 +++++-------- arch/arm/mach-omap2/dma.c | 183 ++++++-------- arch/arm/plat-omap/dma.c | 17 +- drivers/dma/omap-dma.c | 653 ++++++++++++++++++++++++++++++++++++++++----- include/linux/omap-dma.h | 25 ++- 5 files changed, 774 insertions(+), 287 deletions(-) -- FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up.
