2012-03-21dmaengine/dma_slave: introduce inline wrappersAlexandre Bounine
Add inline wrappers for device_prep_slave_sg() and device_prep_dma_cyclic() interfaces to hide new parameter from current users of affected interfaces. Convert current users to use new wrappers instead of direct calls. Suggested by Russell King [https://lkml.org/lkml/2012/2/3/269].

2012-03-19OMAP : SPI : use devm_* functionsShubhrajyoti D
The various devm_* functions allocate memory that is released when a driver detaches. This patch uses devm_request_and_ioremap to request memory in probe function. Since the freeing is not needed the calls are deleted from remove function.Also use use devm_kzalloc for the cs memory allocation. Signed-off-by: Shubhrajyoti D <shubhrajyoti@ti.com>

Current sh-hspi had wrong write/read method which was not linux standard. If spi_transfer requests tx[2], rx[2] len=2, then, driver should run tx[0], rx[0], tx[1], rx[1].

2012-03-07spi: create a message queueing infrastructureLinus Walleij
This rips the message queue in the PL022 driver out and pushes it into (optional) common infrastructure. Drivers that want to use the message pumping thread will need to define the new per-messags transfer methods and leave the deprecated transfer() method as NULL. Most of the design is described in the documentation changes that are included in this patch. Since there is a queue that need to be stopped when the system is suspending/resuming, two new calls are implemented for the device drivers to call in their suspend()/resume() functions: spi_master_suspend() and spi_master_resume(). ChangeLog v1->v2: - Remove Kconfig entry and do not make the queue support optional at all, instead be more agressive and have it as part of the compulsory infrastructure. - If the .transfer() method is implemented, delete print a small deprecation notice and do not start the transfer pump. - Fix a bitrotted comment. ChangeLog v2->v3: - Fix up a problematic sequence courtesy of Chris Blair. - Stop rather than destroy the queue on suspend() courtesy of Chris Blair.

2012-01-21spi/s3c64xx: Log error interruptsMark Brown
Although the hardware supports interrupts we're not currently using them at all since for small transfers the overhead is greater than that for busy waiting and for large transfers we have interrupts from the DMA. This means that if the hardware reports an error (especially one which might not stall transfer) we might miss it. Take a first pass at dealing with such errors by enabling the interrupt if we can and logging the errors if they happen. Ideally we'd report the error via the affected transfer but since we're in master mode it's very difficult to trigger errors at present and this code is much simpler.
