The 64-bit set of updates this release cycle adds support for three new platforms:
- Samsunc Exynos 7
- Freescale LS2085a
- Mediatek MT8173
For all these, the changes mostly consititude additions of DT contents,
but also some Kconfig entries to allow dependency/selection of drivers
per-platform, etc.

DT changes continue to be the bulk of our merge window contents.
We continue to have a large set of changes across the board as new platforms
and drivers are added.
Some of the new platforms are:
- Alphascale ASM9260
- Marvell Armada 388
- CSR Atlas7
- TI Davinci DM816x
- Hisilicon HiP01
- ST STiH418
There have also been some sweeping changes, including relicensing of DTS
contents from GPL to GPLv2+/X11 so that the same files can be reused in
other non-GPL projects more easily. There's also been changes to the
DT Makefile to make it a little less conflict-ridden and churny down
the road.

N.B. The nvidia,tegra20-timer compatible string is removed from the
nvidia,tegra30-timer.txt documentation file because it's already
mentioned in the nvidia,tegra20-timer.txt documentation file.
This second version takes into account the following requests from
Rob Herring <robherring2@gmail.com>:
- Per-IP block patches have been combined into a single patch
- Explicit documentation about which compatible strings are actually
matched by the driver has been removed. In its place is implicit
documentation that loosely follows Rob's prescribed format:
"Must contain '"nvidia,<chip>-pcie", "nvidia,tegra20-pcie"' where
<chip> is tegra30, tegra132, ..." [...] "You should attempt to
document known values of <chip> if you use it"

Make the map match the reality, the current binding text is
nonsense:
- The clock required for the clocking of the serial port
must come first and is not optional (as the driver will
otherwise proceed to grab and use the apb_pclk as uartclk),
and the apb_pclk that clocks the logic must come second
as the code will retrieve the first clock by index,
whereas the PrimeCell but will explicitly look for
"apb_pclk" so this can be specified later, as it is
looked up by name.
- The pin control state "default" is the only mandated
state, the sleep state is entirely optional.
We also add an example to avoid further confusion.

Dedicated CTS and RTS pins are unusable together with a lot of other
peripherals because they share the same line. Pinctrl is limited.
Moreover, the AUART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.
This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

Newer WonderMedia chips introduced another flag in the UART line control
register, which controls whether RTS/CTS signalling should be handled in
the driver or by the hardware itself.
This patch ensures that the kernel can control RTS/CTS (including
disabling it altogether) by forcing this flag to software mode on affected
chips (only WM8880 so far).
Also remove the redundant copy of the binding doc, while we are here.

This reverts commit 06aa82e498.
This commit purports to enable auto CTS flow control for the 8250
UART driver. However, the 8250 UART driver already supports auto
CTS flow control via UART_CAP_AFE and UART_CAP_EFR. Indeed, this
patch introduces another DT attribute for which an existing firmware
flag already exists ("auto-flow-control"). Furthermore, the use of
UPF_HARD_FLOW requires the UART driver to define .throttle and
.unthrottle methods, neither of which are defined for the 8250 UART
driver (which will result in a NULL ptr dereference). Finally, this patch
supposes to fix existing bugs in the serial core for auto CTS-enabled
hardware, but does not include the class of hardware for which these
bugs exist.

mctrl_gpio helpers allow us to create GPIO bindings for any of modem/tty

Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new platforms,
but there's also a bit of cleanup and code removal for things that
are moved from platform code to DT contents (some OMAP clock code in
particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no particular
order:
* Rockchip RK3288 SoC support, including DTS for a dev board that they
have seeded with some community developers.
* Better support for Hardkernel Exynos4-based ODROID boards.
* CCF conversions (and dtsi contents) for several Renesas platforms.
* Gumstix Pepper (TI AM335x) board support
* TI eval board support for AM437x
* Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an Ippo
tablet with the chipset.
* Allwinner A31 Hummingbird board support, not to be confused with the
SolidRun i.MX-based Hummingboard.
* Tegra30 Apalis board support

Pull ARM SoC device-tree changes from Olof Johansson:
"Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new
platforms, but there's also a bit of cleanup and code removal for
things that are moved from platform code to DT contents (some OMAP
clock code in particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no
particular order:
- Rockchip RK3288 SoC support, including DTS for a dev board that
they have seeded with some community developers.
- Better support for Hardkernel Exynos4-based ODROID boards.
- CCF conversions (and dtsi contents) for several Renesas platforms.
- Gumstix Pepper (TI AM335x) board support
- TI eval board support for AM437x
- Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an
Ippo tablet with the chipset.
- Allwinner A31 Hummingbird board support, not to be confused with
the SolidRun i.MX-based Hummingboard.
- Tegra30 Apalis board support"

UART modules on some SoCs only differ in the fifosize of each
UART channel. Its useless to duplicate the drv_data structure
or create a compatible name for such a change.
We can get fifosize via the device tree nodes (not mandating it).

8250 uart driver currently supports only software assisted hw flow
control. The software assisted hw flow control maintains a hw_stopped
flag in the tty structure to stop and start transmission and use modem
status interrupt for the event to drive the handshake signals. This is
not needed if hw has flow control capabilities. This patch adds a
DT attribute for enabling hw flow control for a uart port. Also skip
stop and start if this flag is present in flag field of the port
structure.

On sam9x5, dedicated CTS (and RTS) pins are unusable together with the
LCDC, the EMAC, or the MMC because they share the same line.
Moreover, the USART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.
This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

These cleanup patches are mainly move stuff around and should all
be harmless. They are mainly split out so that other branches can
be based on top to avoid conflicts.
Notable changes are:
* We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used. (Uwe Kleine-König)
* The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions. (Kumar Gala)
* A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
* Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
* mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
* at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people).

To make this work some code out of arch/arm needed to be adapted. The
respective changes got acks by their maintainers to be taken via armsoc

Compared to the previous pull request there was another patch added that
