2013-07-16ARM: edma: remove duplicated include from edma.cWei Yongjun

2013-06-24ARM: edma: Add EDMA crossbar event mux supportMatt Porter
EDMA supports a cross bar which provides ability to mux additional events into physical channels present in the channel controller. This is required when the number of events present in the system are more than number of available physical channels. Changes by Joel: * Split EDMA xbar support out of original EDMA DT parsing patch to keep it easier for review. * Rewrite shift and offset calculation.

2013-06-24ARM: edma: Add DT and runtime PM support to the private EDMA APIMatt Porter
Adds support for parsing the TI EDMA DT data into the required EDMA private API platform data. Enables runtime PM support to initialize the EDMA hwmod. Enables build on OMAP. Changes by Joel: * Setup default one-to-one mapping for queue_priority and queue_tc mapping as discussed in [1]. * Split out xbar stuff to separate patch. [1] * Dropped unused DT helper to convert to array * Fixed dangling pointer issue with Sekhar's changes [1] https://patchwork.kernel.org/patch/2226761/ Signed-off-by: Matt Porter <mporter@ti.com> [nsekhar@ti.com: fix checkpatch errors, build breakages.

2013-06-18ARM: edma: Convert to devm_* apiLad, Prabhakar
Use devm_ioremap_resource instead of reques_mem_region()/ioremap(), devm_request_irq() instead of request_irq() and kzalloc() calls to devm_kzalloc(). This ensures more consistent error values and simplifies error paths.

2013-06-18ARM: edma: remove unused transfer controller handlersMatt Porter
Fix build on OMAP, the irqs are undefined on AM33xx. These error interrupt handlers were hardcoded as disabled so since they are unused code, simply remove them. Signed-off-by: Matt Porter <mporter@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
2013-06-18ARM: davinci: move private EDMA API to arm/commonMatt Porter
Move mach-davinci/dma.c to common/edma.c so it can be used by OMAP (specifically AM33xx) as well.
