include/linux/dw_spi.h only includes driver internal data. It doesn't
expose a platform_data configuration structure or similar (at least
nothing in-tree). This patch moves the header into drivers/spi so
that the scope is limited to only the dw_spi_*.c driver files

Add linux/scatterlist.h include to dw_spi.h, because we need to know

Introduce a driver for the Texas Instruments TSC2005 touchscreen
controller (http://focus.ti.com/docs/prod/folders/print/tsc2005.html).
The patch is based on a driver by Lauri Leukkunen, with modifications

mpc23s17 is very similar to the mcp23s08, except that registers are 16bit
wide, so extend the interface to work with both variants.
The s17 variant also has an additional address pin, so adjust platform
data structure to support up to 8 devices per SPI chipselect.

Some platform attributes (e.g. max_hz, use_dma) were being intuited
from the modem type. These things should be specified by the platform
data.
Added max_hz, use_dma to ifx_modem_platform_data definition,
replaced is_6160 w/ modem_type, and changed clients accordingly

dw_spi driver in upstream only supports PIO mode, and this patch
will support it to cowork with the Designware dma controller used
on Intel Moorestown platform, at the same time it provides a general
framework to support dw_spi core to cowork with dma controllers on
other platforms
It has been tested with a Option GTM501L 3G modem and Infenion 60x60
modem. To use DMA mode, DMA controller 2 of Moorestown has to be enabled
Also change the dma interface suggested by Linus Walleij.

Sodaville's SPI controller is very much the same as in PXA25x. The
difference:
- The RX/TX FIFO is only 4 words deep instead of 16
- No DMA support
- The SPI controller offers a CS functionality

The PXA-SPI driver relies on some files / defines which are arm specific
and are within the ARM tree. The CE4100 SoC which is x86 has also the
SPI core.
This patch moves the ssp and spi files from arm/mach-pxa and plat-pxa to
include/linux where the CE4100 can access them.
This move got verified by building the following defconfigs:
cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig
imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig
raumfeld_defconfig magician_defconfig

Currently spi_register_board_info() has to be called before its related
spi_master be registered, otherwise these board info will be just ignored.
This patch will remove this order limit, it adds a global spi master list
like the existing global board info listr. Whenever a board info or a
spi_master is registered, the spi master list or board info list
will be scanned, and a new spi device will be created if there is a
master-board info match.

commit 052dc7c45i "spi/dw_spi: conditional transfer mode change"
introduced cs_control code, which has a bug by using bit offset
for spi mode to set transfer mode in control register. Also it
forces devices who don't need cs_control to re-configure the
control registers for each spi transfer. This patch will fix them
