Add support for the QSPI controller found some on Freescale/Motorola
Coldfire MCUs.Full duplex, active high cs, spi modes 0-3 and word sizes 8-16 bits are
supported. The hardware drives the MISO, MOSI and SCLK lines, but the chip
selects are managed via GPIO and must be configured by the board code.The QSPI controller has an 80 byte buffer which allows us to transfer up to 16
words at a time. For transfers longer than 16 words, we split the buffer in
half so we can update in one half while the controller is operating on the
other half. Interrupt latencies then ultimately limits our sustained thru-put
to something less than half the maximum speed supported by the part.Signed-off-by: Steven King

Each SPI controller has exactly one CS line and as such doesn't
provide for multi-cs. We implement a workaround to support
multi-cs by _not_ configuring the mux'ed CS pin for each SPI
controller. The CS mechanism is assumed to be fully machine
specific - the driver doesn't even assume some GPIO pin is used
to control the CS.The driver selects between DMA and POLLING mode depending upon
the xfer size - DMA mode for xfers bigger than FIFO size, POLLING
mode otherwise.The driver has been designed to be capable of running SoCs since
s3c64xx and till date, for that reason some of the register fields
have been passed via, SoC specific, platform data.Signed-off-by: Jassi Brar

Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver
to get DMA-like performance where there are either no free DMA channels or
when doing transfers that required both TX and RX data paths.Since this patch requires the addition of an assembly file to hold the FIQ
code, we rename the module (instead of adding a rename of the .c file to
this patch). We expect most users are loading this via udev and thus
there should be no change to the userland configuration.Signed-off-by: Ben Dooks

This change adds the OMAP SPI 100k driver created by
Fabrice Crohas . This SPI bus is found on
OMAP7xx-series smartphones, and for many, the touchscreen is
attached to this bus.The lion's share of the work was done by Fabrice on this driver --
I am merely porting it from the Linwizard project on his behalf.Signed-off-by: Cory Maccarrone

This patch is V2 of SPI Master support for the SuperH MSIOF.
Full duplex, spi mode 0-3, active high cs, 3-wire and lsb
first should all be supported, but the driver has so far
only been tested with "mmc_spi".The MSIOF hardware comes with 32-bit FIFOs for receive and
transmit, and this driver simply breaks the SPI messages
into FIFO-sized chunks. The MSIOF hardware manages the pins
for clock, receive and transmit (sck/miso/mosi), but the chip
select pin is managed by software and must be configured as
a regular GPIO pin by the board code.Performance wise there is still room for improvement, but
on a Ecovec board with the built-in sh7724 MSIOF0 this driver
gets Mini-sd read speeds of about half a megabyte per second.Future work include better clock setup and merging of 8-bit
transfers into 32-bit words to reduce interrupt load and
improve throughput.Signed-off-by: Magnus Damm

This patch adds in support for the DS570 IP.
It's register compatible with the DS464, but adds support for 8/16/32 SPI.
The 8/16/32 support is added by attaching callbacks reading/writing the
proper amount of data. To indicate to the driver which amount of bits
to use a new field is introduced in the platform data struct.Acked-by: Grant Likely

This patch changes the out_(be)(8|16|32) and in_(be)(8|16|32) calls to 32 bits ioread/iowrite.
The read and write function are attached to the internal struct as callbacks, callback
is selected depending on endianess.This will also build on platforms not supporting the in/out calls for instance x86.

This patch adds QE buffer descriptors mode support for the
spi_mpc8xxx driver, and as a side effect we now support CPM1
and CPM2 SPI controllers.That means that today we support almost all MPC SPI controllers:
- MPC834x-style controllers (support PIO mode only);
- CPM1 and CPM2 controllers (support DMA mode only);
- QE SPI controllers in CPU mode (PIO mode with shift quirks);
- QE SPI controllers in buffer descriptors (DMA) mode;The only controller we don't currently support is a newer eSPI
(with a dedicated chip selects and a bit different registers map).Signed-off-by: Anton Vorontsov

Generalize the old at91rm9200 "bootstrap" bitbanging SPI master driver as
"spi_gpio", so it works with arbitrary GPIOs and can be configured through
platform_data. Such SPI masters support:- any number of bus instances (bus_num is the platform_device.id)
- any number of chipselects (one GPIO per spi_device)
- all four SPI_MODE values, and SPI_CS_HIGH
- i/o word sizes from 1 to 32 bits;
- devices configured as with any other spi_master controllerWhen configured using platform_data, this provides relatively low clock
rates. On platforms that support inlined GPIO calls, significantly
improved transfer speeds are also possible with a semi-custom driver.
(It's still painful when accessing flash memory, but less so.)Sanity checked by using this version to replace both native controllers on
a board with six different SPI slaves, relying on three different
SPI_MODE_* values and both SPI_CS_HIGH settings for correct operation.[akpm@linux-foundation.org: cleanups]
