2014-04-22dmaengine: edma: Add DMA memcpy supportJoel Fernandes
We add DMA memcpy support to EDMA driver. Successful tests performed using dmatest kernel module. Copy alignment is set to DMA_SLAVE_BUSWIDTH_4_BYTES and users must ensure length is aligned so that copy is performed fully.

2014-04-22dmaengine: edma: Prefix debug prints where the text were identical in prep ↵Peter Ujfalusi
callbacks prep_slave_sg and prep_dma_cyclic callbacks have mostly same failure cases with the same texts printed in case we hit them. It helps when debugging if we know exactly which callback generated the errors. At the same time change the debug level for descriptor allocation failure from dbg to err since all other error cases are dev_err and this failure is similarly fatal as the other ones.

2014-04-16platform: Fix timberdale dependenciesJean Delvare
VIDEO_TIMBERDALE selects TIMB_DMA which itself depends on MFD_TIMBERDALE, so VIDEO_TIMBERDALE should either select or depend on MFD_TIMBERDALE as well. I chose to make it depend on it because I think it makes more sense and it is consistent with what other options are doing. Adding a "|| HAS_IOMEM" to the TIMB_DMA dependencies silenced the kconfig warning about unmet direct dependencies but it was wrong: without MFD_TIMBERDALE, TIMB_DMA is useless as the driver has no device to bind to.

2014-04-14dma: edma: fix incorrect SG list handlingSekhar Nori
The code to handle any length SG lists calls edma_resume() even before edma_start() is called. This is incorrect because edma_resume() enables edma events on the channel after which CPU (in edma_start) cannot clear posted events by writing to ECR (per the EDMA user's guide). Because of this EDMA transfers fail to start if due to some reason there is a pending EDMA event registered even before EDMA transfers are started. This can happen if an EDMA event is a byproduct of device initialization. Fix this by calling edma_resume() only if it is not the first batch of MAX_NR_SG elements. Without this patch, MMC/SD fails to function on DA850 EVM with DMA. The behaviour is triggered by specific IP and this can explain why the issue was not reported before (example with MMC/SD on AM335x). Tested on DA850 EVM and AM335x EVM-SK using MMC/SD card.

In mv_xor_status(), we are currently calling mv_xor_clean_completed_slots() when the transaction is complete (the cookie status is DMA_COMPLETE). However, a completed status means that mv_xor_slot_cleanup() was called, which cleans the completed slots. In other words, there's nothing to cleanup for a completed transaction in mv_xor_status().

Add the DMA engine driver for the QCOM Bus Access Manager (BAM) DMA controller found in the MSM 8x74 platforms. Each BAM DMA device is associated with a specific on-chip peripheral. Each channel provides a uni-directional data transfer engine that is capable of transferring data between the peripheral and system memory (System mode), or between two peripherals (BAM2BAM).
