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).
This patch is just some changes to use direction defines
which is used in samsung DMA operation.

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.

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.

This switches the PL022 worker to a kthread in order to get
hold of a mechanism to control the message pump priority. On
low-latency systems elevating the message kthread to realtime
priority give a real sleek response curve. This has been
confirmed by measurements. Realtime priority elevation for
a certain PL022 port can be requested from platform data.

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.

This patch fixes an (ACPI S3) suspend regression introduced in commit
68d6e6713fcb ("tpm: Introduce function to poll for result of self test")
and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers
active.
The suspend problem occurred if the TPM was disabled and/or deactivated
and therefore the TPM_PCRRead checking the result of the (asynchronous)
self test returned an error code which then caused the tpm_tis driver to
become inactive and this then seemed to have negatively influenced the
suspend support by the tpm_infineon driver... Besides that the tpm_tis
drive may stay active even if the TPM is disabled and/or deactivated.

The type of 'make_request_fn' changed in 5a7bbad27a4 ("block: remove

Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
enabled. However, kdump only enables one CPU in the new environment,
thus causing tg3 to abort MSI-X setup. When the driver attempts to
enable INTA or MSI interrupt modes on a kdump kernel, interrupt
delivery fails.
This patch attempts to workaround the problem by forcing the driver
to enable a single MSI-X interrupt. In such a configuration, the
device's multivector interrupt mode must be disabled.
