Wolfram Sang 14ac00e033 spi: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the

Mark A. Greer 97ca0d6cc1 spi: omap2-mcspi: Configure hardware when slave driver changes mode
Commit id 2bd16e3e23
(spi: omap2-mcspi: Do not configure the controller
on each transfer unless needed) does its job too
well so omap2_mcspi_setup_transfer() isn't called
even when an SPI slave driver changes 'spi->mode'.
The result is that the mode requested by the SPI
slave driver never takes effect.

Fix this by adding the 'mode' member to the
omap2_mcspi_cs structure which holds the mode
value that the hardware is configured for.
When the SPI slave driver changes 'spi->mode'
it will be different than the value of this new
member and the SPI master driver will know that
the hardware must be reconfigured (by calling
omap2_mcspi_setup_transfer()).

Fixes: 2bd16e3e23 (spi: omap2-mcspi: Do not configure the controller on each transfer unless needed)

Currently a divide-by-2^n clock is used, causing a very coarse

Victor Kamensky 21b2ce5e99 spi: omap2-mcspi: raw read and write endian fix
All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.

Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

The MCSPI controller has a built-in FIFO buffer to unload the DMA or interrupt

For SPI transfers in DMA mode, the largest possible FIFO buffer size will be

if: calculated FIFO buffer size is less then 2 bytes or the FIFO buffer size
isn't multiple of the SPI word length.

Linus Torvalds 5e090ed7af ARM: soc: late platform updates
This branch contains updates to OMAP and Marvell platforms (kirkwood,
 dove, mvebu) that came in after we had done the big multiplatform merges,
 so they were kept separate from the rest, and not separated into the
 traditional topics of cleanup/driver/platform features.
 
 For OMAP, the updates are:
 - Runtime PM conversions for the GPMC and RNG IP blocks
 - Preparation patches for the OMAP common clock framework conversion
 - clkdev alias additions required by other drivers
 - Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4
 - OMAP hwmod code and data improvements
 - Preparation patches for the IOMMU runtime PM conversion
 - Preparation patches for OMAP4 full-chip retention support
 
 For Kirkwood/Dove/mvebu:
 
 - New driver for "address decoder controller" for mvebu, which
   is a piece of hardware that configures addressable devices and
   peripherals. First user is the boot rom aperture on armada XP since
   it is needed for SMP support.
 - New device tree bindings for peripherals such as gpio-fan, iconnect
   nand, mv_cesa and the above address decoder controller.
 - Some defconfig updates, mostly to enable new DT boards and a few drivers.
 - New drivers using the pincontrol subsystem for dove, kirkwood and mvebu
 - New clean gpio driver for mvebu

Merge tag 'soc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull late ARM soc platform updates from Olof Johansson:
 "This branch contains updates to OMAP and Marvell platforms (kirkwood,
  dove, mvebu) that came in after we had done the big multiplatform
  merges, so they were kept separate from the rest, and not separated
  into the traditional topics of cleanup/driver/platform features.

  For OMAP, the updates are:
   - Runtime PM conversions for the GPMC and RNG IP blocks
   - Preparation patches for the OMAP common clock framework conversion
   - clkdev alias additions required by other drivers
   - Performance Monitoring Unit (PMU) support for OMAP2, 3, and
     non-4430 OMAP4
   - OMAP hwmod code and data improvements
   - Preparation patches for the IOMMU runtime PM conversion
   - Preparation patches for OMAP4 full-chip retention support

  For Kirkwood/Dove/mvebu:
   - New driver for "address decoder controller" for mvebu, which is a
     piece of hardware that configures addressable devices and
     peripherals.  First user is the boot rom aperture on armada XP
     since it is needed for SMP support.
   - New device tree bindings for peripherals such as gpio-fan, iconnect
     nand, mv_cesa and the above address decoder controller.
   - Some defconfig updates, mostly to enable new DT boards and a few
     drivers.
   - New drivers using the pincontrol subsystem for dove, kirkwood and
     mvebu
   - New clean gpio driver for mvebu"

Linus Torvalds 7fe0b14b72 spi: Updates for v3.7
No framework work here, only a bunch of driver updates of varying sizes:
 
 - Factoring out of the core hardware support from the MXS MMC driver by
   Marek Vasut to allow the hardware to also be used for SPI.
 - Lots of error handling cleanups from Guenter Roeck
 - Removal of the existing Tegra driver which is quite comprehensively
   broken as detailed in the changelog for the removal.
 - DT suppport for the PL022 and GPIO drivers.
 - pinctrl support for OMAP and PL022.

Linus Torvalds 61464c8357 ARM: soc: general cleanups
This is a large branch that contains a handful of different cleanups:
 
 - Fixing up the I/O space remapping on PCI on ARM. This is a series
   from Rob Herring that restructures how all pci devices allocate I/O
   space, and it's part of the work to allow multiplatform kernels.
 - A number of cleanup series for OMAP, moving and removing some
   headers, sparse irq rework and in general preparation for
   multiplatform.
 - Final removal of all non-DT boards for Tegra, it is now
   device-tree-only!
 - Removal of a stale platform, nxp4008. It's an old mobile chipset
   that is no longer in use, and was very likely never really used with
   a mainline kernel. We have not been able to find anyone interested
   in keeping it around in the kernel.
 - Removal of the legacy dmaengine driver on tegra
 
 + A handful of other things that I haven't described above.
