Pull MIPS updates from Ralf Baechle:
 "More hardware support across the field including a bunch of device
  drivers.  The highlight however really are further steps towards
  device tree.

  This has been sitting in -next for ages.  All MIPS _defconfigs have
  been tested to boot or where I don't have hardware available, to at
  least build fine."

0082c16e3a spi: Updates for 3.6
Since Grant is even more specacularly busy than usual for the time being
 I've been collecting SPI patches for him for this release - probably
 things will revert back to Grant before the next release.  There's
 nothing too exciting here, mostly it's simple driver specific stuff:
 
 - Add spi: to the modaliases of SPI devices to provide namespacing.
 - A driver for AD-FMCOMMS1-EBZ.
 - DT binding for Orion.
 - Fixes and cleanups for i.MX, PL0022, OMAP and bitbang drivers.
 
 There may be a few more fixes I've missed, people keep sending me new
 things.

6cd3c7e2b1 SPI: MIPS: lantiq: add FALCON spi driver
The external bus unit (EBU) found on the FALCON SoC has spi emulation that is
designed for serial flash access. This driver has only been tested with m25p80
type chips. The hardware has no support for other types of spi peripherals.

d9ddcec35d spi/fsl-espi: disable CONFIG_SPI_FSL_ESPI=m build
When spi_fsl_espi is chosen to be built as a module, there is a build
error because we test only CONFIG_SPI_FSL_ESPI in declaration of
struct mpc8xxx_spi in drivers/spi/spi_fsl_lib.h. Also some called
functions are not exported.

So we forbid CONFIG_SPI_FSL_ESPI to be tristate here.

The error looks like:

Replace them with MIPS_ALCHEMY in the various Kconfig files.  Finally
delete them altogether from the Alchemy Kconfig file.

04ee585495 spi/imx: use soc name in spi device type naming scheme
Software defined version number is not stable enough to be used
in device type naming scheme.  The patch changes it to use implicit
soc name for spi device type definition.  In this way, we can easily
align the naming scheme with device tree binding, which comes later.

It removes fifosize from spi_imx_data and adds devtype there, so that
fifosize can be set in an inline function according to devtype.
Also, cpu_is_mx can be replaced by inline functions checking devtype.

2a64a90a2c spi/imx: merge type SPI_IMX_VER_0_7 into SPI_IMX_VER_0_4
The only difference between SPI_IMX_VER_0_7 and SPI_IMX_VER_0_4 is
.config function.  The patch uses cpu_is_mx35 (to be removed) as the
temporary solution to consolidate functions spi_imx0_4_config and
spi_imx0_7_config into mx31_config.  As a result, type SPI_IMX_VER_0_7
can be merged into SPI_IMX_VER_0_4.

It also renames function spi_imx0_4_reset to mx31_reset to keep
consistency with other function naming.

A couple of redundant macros, MX3_CSPISTAT and MX3_CSPISTAT_RR,
together with the useless type SPI_IMX_VER_0_5 also get cleaned up.

ca632f5566 spi: reorganize drivers
Sort the SPI makefile and enforce the naming convention spi_*.c for
spi drivers.

This change also rolls the contents of atmel_spi.h into the .c file
since there is only one user of that particular include file.

v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be
      be the predominant pattern for subsystem prefixes.
    - Clean up filenames in Kconfig and header comment blocks

9c3e737561 spi/spi_bfin_sport: new driver for a SPI bus via the Blackfin SPORT peripheral
The Blackfin SPORT peripheral is a pretty flexible device.  With enough
coaching, we can make it generate SPI compatible waveforms.  This is
desirable as the SPORT can run at much higher clock frequencies than the
dedicated on-chip SPI peripheral, and it can do full duplex DMA.  It also
opens up the possibility of multiple SPI buses in case someone wants to
dedicate a whole bus to a specific part that does not play well with
others.
