Commit 178db7d3, "spi: Fix device unregistration when unregistering the bus master", changed device initialization to be children of the bus master, not children of the bus masters parent device. The pdata pointer used in fsl_spi_chipselect must updated to reflect the changed initialization.

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].

I found that there are two kind of direction type. First one is dma_data_direction defined in include/linux/dma-direction.h. It is used for parameter of dma_map/unmap_single in spi-s3c64xx. The other one is dma_transter_direction defined in include/linux/dmaengine.h. It is used for direction of samsung DMA operation (arch/arm/plat-samsung/dma-ops.c).

Some systems have SPI devices located on plugin modules which are enumerated at runtime as devices. The drivers for these plugin modules need to register their SPI devices at probe() time so want to be able to call spi_register_board_info() but that function is currently marked as __init rather than __devinit so this usage isn't legal. Change the annotation to __devinit to handle this. Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

由 Linus Walleij 提交于
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.
