Pull ARM DT updates from Olof Johansson:
 "As always, this tends to be one of our bigger branches.  There are
  lots of updates this release, but not that many jumps out as something
  that needs more detailed coverage.  Some of the highlights are:

   - DTs for the new Annapurna Labs Alpine platform

   - more graphics DT pieces falling into place on Exynos, bridges,
     clocks.

   - plenty of DT updates for Qualcomm platforms for various IP blocks

   - some churn on Tegra due to switch-over to tool-generated pinctrl
     data

   - misc fixes and updates for Atmel at91 platforms

   - various DT updates to add IP block support on Broadcom's Cygnus
     platforms

   - more updates for Renesas platforms as DT support is added for
     various IP blocks (IPMMU, display, audio, etc)"

Pull ARM SoC cleanups from Olof Johansson:
 "We've got a fairly large cleanup branch this time.  The bulk of this
  is removal of non-DT platforms of several flavors:

   - Atmel at91 platforms go full-DT, with removal of remaining
     board-file based support

   - OMAP removes legacy board files for three more platforms

   - removal of non-DT mach-msm, newer Qualcomm platforms now live in
     mach-qcom

   - Freescale i.MX25 also removes non-DT platform support"

Most of the rest of the changes here are fallout from the above, i.e. for
example removal of drivers that now lack platforms, etc.

Merge "wireless wl12xx and omap device tree changes for v4.1" from Tony
Lindgren:

Wireless and omap changes to make wl12xx driver to use device tree
data instead of platform data from Eliad Peller &lt;eliad@wizery.com&gt;:

- Add device-tree support to the wlcore (wl12xx/wl18xx) driver.

- Update the current users to use the bindings instead of pdata-quirks.

- Finally, remove the deprecated wl12xx_platform_data struct

Note that da850 board file code that still uses the platform data,
but we have da850.dtsi that can be used instead. So it was decided
that we should try to remove the wl12xx support from the da850
board file as suggested by Sekhar Nori &lt;nsekhar@ti.com&gt;. As it's
the last patch in the series, the last patch can be simply reverted
if needed.

As this series touches quite a bit of arch code, it was suggested
by Kalle Valo &lt;kvalo@codeaurora.org&gt; that the whole series should
be merged via the arm-soc tree.

* tag 'omap-for-v4.1/wl12xx-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  wlcore: remove wl12xx_platform_data

  dt: bindings: add TI's wilink wireless device
  wl12xx: use frequency instead of enumerations for pdata clocks

<content type='text'>
This patchset attempts to standardize the naming of dt-bindings
documents based on the Broadcom vendor prefix of brcm.

Although there are no guidelines currently present for how to name
the dt-bindings document the "vendor,binding.txt" style is in use by
some of the other vendors.

The file of-serial.txt was only for 8250 compatible UART implementations,
so renamed it to 8250.txt to avoid confusing other persons.

Fixed behaviour of get_mctrl() serial driver function as documented in:
https://www.kernel.org/doc/Documentation/serial/driver

Added device-tree properties 'dcd-override', 'dsr-override',
'cts-override', and 'ri-override' specific to the Synopsis 8250
DesignWare UART driver. Allows one to force Data Carrier Detect,
Clear To Send, and Data Set Ready signals to permanently be reported as
active. The Ring indicator can be forced to be reported as inactive.

It is possible that if modem control signalling is enabled on a port
that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the
driver can hang indefinitely waiting for the state to change. The new
DT properties allow the driver to ignore the state of these pins on
serial ports that don't support them, as recommended in the kernel
documentation.
