72ae6e4b31 dmaengine: at_hdmac: extend hardware handshaking interface identification
Peripheral handshaking identification numbers can be bigger than 15, so new
fields have been created in the CFG register.
Add macros to take this modification into account and use them in
at_dma_xlate() function.

0bf6a210a4 Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver specific changes from Arnd Bergmann:
 "These changes are all driver specific and cross over between arm-soc
  contents and some other subsystem, in these cases cpufreq, crypto,
  dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have
  these changes merged through arm-soc.

  As we proceed to untangle the dependencies between platform code and
  driver code, the amount of changes in this category is fortunately
  shrinking, for 3.11 we have 16 branches here and 101 non-merge
  changesets, the majority of which are for the stedma40 dma engine
  driver used in the ux500 platform.  Cleaning up that code touches
  multiple subsystems, but gets rid of the dependency in the end.

  The mailbox code moved out from mach-omap2 to drivers/mailbox is an
  intermediate step and is still omap specific at the moment.  Patches
  exist to generalize the subsystem and add other drivers with the same
  API, but those did not make it for 3.11."

3883cbb6c1 Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC specific changes from Arnd Bergmann:
 "These changes are all to SoC-specific code, a total of 33 branches on
  17 platforms were pulled into this.  Like last time, Renesas sh-mobile
  is now the platform with the most changes, followed by OMAP and
  EXYNOS.

  Two new platforms, TI Keystone and Rockchips RK3xxx are added in this
  branch, both containing almost no platform specific code at all, since
  they are using generic subsystem interfaces for clocks, pinctrl,
  interrupts etc.  The device drivers are getting merged through the
  respective subsystem maintainer trees.

  One more SoC (u300) is now multiplatform capable and several others
  (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
  towards that goal with this series but need more work.

  Also noteworthy is the work on PCI here, which is traditionally part
  of the SoC specific code.  With the changes done by Thomas Petazzoni,
  we can now more easily have PCI host controller drivers as loadable
  modules and keep them separate from the platform code in
  drivers/pci/host.  This has already led to the discovery that three
  platforms (exynos, spear and imx) are actually using an identical PCIe
  host controller and will be able to share a driver once support for
  spear and imx is added."

2646a0e52b ARM: edma: Add EDMA crossbar event mux support
EDMA supports a cross bar which provides ability

present in the channel controller.

This is required when the number of events present

* Split EDMA xbar support out of original EDMA DT parsing patch

From Tony Lindgren:

Move OMAP Mailbox framework to drivers via Suman Anna <s-anna@ti.com>

The OMAP Mailbox driver framework is moved out of arch/arm folder
into drivers/mailbox folder, to re-enable building it and also serve
as a baseline for adapting to the new mailbox driver framework. The
changes mainly contain:
  - a minor bug fix and cleanup of mach-specific mailbox code
  - remove any header dependencies from plat-omap for multi-platform
    support
  - represent mailbox device data through platform data/hwmod attrs
  - move the omap mailbox code out of plat-omap/mach-omapX to
    drivers/mailbox folder

DaVinci SoC changes for v3.11

This pull request moves DaVinci EDMA library to
arch/arm/common so it can be used by OMAP based AM335x.
This is a temporary step until all drivers are converted
to use the dmaengine driver in drivers/dma/edma.c.

Several drivers like SPI, MMC/SD have already been converted.
Some like audio are pending.

The other two patches in the pull request are cleanup in nature.

The different generations of OMAP2+ SoCs have almost the same
mailbox IP, but the IP has configurable parameters for number
of users (interrupts it can generate out towards processors)
and number of fifos (the base unidirectional h/w communication
channel). This data cannot be read from any registers, and so
has been added to the platform data.

This data together with the interrupt-type configuration can be
used in properly figuring out the number of registers to save
and restore in the OMAP mailbox driver code.

54407f190c phy-rcar-usb: add R8A7778 support
The driver currently only supports R8A7779 SoC. Compared to it, R8A7778 USB-PHY
has extra register range containing two high-speed signal quality characteristic
control registers which should be set up  during USB-PHY  startup depending on
whether a ferrite bead is in use or not.  So, we now handle an optional second
memory range in the driver's probe method, add the 'ferrite_bead' field to the
driver's platform data, and add an extra (optional) step to the USB-PHY startup
routine which sets up the extended registers.

Also mark in the driver's Kconfig section  that R8A7778 is now supported and
generally clarify that section, uppercasing the word "phy" and also changing
the module name that got lost in the big driver rename, while at it...

The patch has been tested on the Marzen and BOCK-W boards.

However, platforms do exist which don't follow this convention, so

43f2e1a3be dmaengine: ste_dma40: Convert data_width from register bit format to value
When a DMA client requests and configures a DMA channel, it requests
data_width in Bytes. The DMA40 driver then swiftly converts it over to
the necessary register bit value. Unfortunately, for any subsequent
calculations we have to shift '1' by the bit pattern (1 << data_width)
times to make any sense of it.

This patch flips the semantics on its head and only converts the value
to its respective register bit pattern when writing to registers. This
way we can use the true data_width (in Bytes) value.

b6b5e76bb8 ASoC: Add ssm2518 support
This patch adds a ASoC CODEC driver for the SSM2516. The SSM2516 is a stereo
Class-D audio amplifier with an I2S interface for audio in and a built-in
dynamic range control processor.

5d489a4351 dmaengine: ste_dma40: Correct copy/paste error
'struct stedma40_half_channel_info's header comment says that it's
called 'struct stedma40_chan_cfg'. Let's straighten that out.

9c3c95147c ARM: ux500: Remove DMA address look-up table
DMA addresses are now passed as part of the dmaengine API by invoking
dmaengine_slave_config(). So there's no requirement for the DMA40
driver to look them up in a table provided by platform data. This
method does not fit in well using Device Tree either.

db72da9210 dmaengine: ste_dma40: Calculate number of logical channels from physical ones
This change will cost ~25KB of memory, but it's worth the trade-off,
as it removes a great deal of overhead. It means that instead of only
allocating memory for the logical channels in use, it does so for all
available ones, which is 32 per physical channel. However, this now
means we can remove some platform data and we don't have to worry
about adding vendor specific variables to Device Tree.
