The s3cmci driver is calling s3c2410_dma_config with incorrect data for the DCON register. The S3C2410_DCON_HWTRIG is implicit in the channel configuration and the device selection of S3C2410_DCON_CH0_SDI is incorrect as the DMA system may not select channel 0.

2009-03-09[ARM] pxa: move DMA registers definitions into <mach/dma.h>Eric Miao
1. Driver code where pxa_request_dma() is called will most likely reference DMA registers as well, and it is really unnecessary to include pxa-regs.h just for this. Move the definitions into <mach/dma.h> and make relevant drivers include it instead of <mach/pxa-regs.h>. 2. Introduce DMAC_REGS_VIRT as the virtual address base for these DMA registers. This allows later processors to re-use the same IP while registers may start at different I/O address. Signed-off-by: Eric Miao <eric.miao@marvell.com>

2009-02-18atmel-mci: fix initialization of dma slave dataDan Williams
The conversion of atmel-mci to dma_request_channel missed the initialization of the channel dma_slave information. The filter_fn passed to dma_request_channel is responsible for initializing the channel's private data. This implementation has the additional benefit of enabling a generic client-channel data passing mechanism.

2009-02-18omap_hsmmc: recover from transfer failuresJean Pihet
Timeouts during a command that has a data phase can result in the next command issued after the command that failed not being processed, i.e. no interrupt ever occurs to indicate the command has completed. This failure can result in a deadlock. This patch resets the data state machine to clear the error in case of a command timeout.

2009-02-18omap_hsmmc: only MMC1 allows HCTL.SDVS != 1.8VDavid Brownell
Based on a patch from Tony Lindgren ... after initialization, never change HCTL.SDVS except for MMC1. The other controller instances only support 1.8V in that field, although they can suport other card/SDIO/eMMC/... voltages with level shifting solutions such as external transceivers. MMC2 behavior sanity tested on Overo/WLAN, OMAP3430 SDP, and custom hardware. MMC1 also sanity tested on those platforms plus Beagle. This also fixes a bug preventing MMC2 (and also presumably MMC3) from powering down when requested.

2009-02-18s3cmci: Fix hangup in do_pio_write()Yauhen Kharuzhy
This commit fixes the regression what was added by commit 088a78af978d0c8e339071a9b2bca1f4cb368f30 "s3cmci: Support transfers which are not multiple of 32 bits." fifo_free() now returns amount of available space in FIFO buffer in bytes. But do_pio_write() writes to FIFO 32-bit words. Condition for return from cycle is (fifo_free() == 0), but when fifo has 1..3 bytes of free space then this condition will never be true and system hangs. This patch changes condition in the while() to (fifo_free() > 3).

2009-01-06dmaengine: up-level reference counting to the module levelDan Williams
Simply, if a client wants any dmaengine channel then prevent all dmaengine modules from being removed. Once the clients are done re-enable module removal. Why?, beyond reducing complication: 1/ Tracking reference counts per-transaction in an efficient manner, as is currently done, requires a complicated scheme to avoid cache-line bouncing effects. 2/ Per-transaction ref-counting gives the false impression that a dma-driver can be gracefully removed ahead of its user (net, md, or dma-slave) 3/ None of the in-tree dma-drivers talk to hot pluggable hardware, but if such an engine were built one day we still would not need to notify clients of remove events. The driver can simply return NULL to a ->prep() request, something that is much easier for a client to handle.
