Pull slave-dmaengine updates from Vinod Koul: "This time we have Andy updates on dw_dmac which is attempting to make this IP block available as PCI and platform device though not fully complete this time. We also have TI EDMA moving the dma driver to use dmaengine APIs, also have a new driver for mmp-tdma, along with bunch of small updates. Now for your excitement the merge is little unusual here, while merging the auto merge on linux-next picks wrong choice for pl330 (drivers/dma/pl330.c) and this causes build failure. The correct resolution is in linux-next.

bool "SPI support"

help
|
|
The "Serial Peripheral Interface" is a low level synchronous
|
|
protocol. Chips that support SPI can have data transfer rates
|
|
up to several tens of Mbit/sec. Chips are addressed with a
|
|
controller and a chipselect. Most SPI slaves don't support
|
|
dynamic device discovery; some are even write-only or read-only.
|
|
|
|
SPI is widely used by microcontrollers to talk with sensors,
|
|
eeprom and flash memory, codecs and various other controller
|
|
chips, analog to digital (and d-to-a) converters, and more.
|
|
MMC and SD cards can be accessed using SPI protocol; and for
|
|
DataFlash cards used in MMC sockets, SPI must always be used.
|
|
|
|
SPI is one of a family of similar protocols using a four wire
|
|
interface (select, clock, data in, data out) including Microwire
|
|
(half duplex), SSP, SSI, and PSP. This driver framework should
|
|
work with most such devices and controllers.

Select this to get SPI support through I/O pins (GPIO, parallel

this code to manage the per-word or per-transfer accesses to the
