git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM driver updates from Olof Johansson:
"Updates of SoC-near drivers and other driver updates that makes more
sense to take through our tree.
The largest part of this is a conversion of device registration for
some renesas shmobile/sh devices over to use resources. This has
required coordination with the corresponding arch/sh changes, and
we've agreed to merge the arch/sh changes through our tree.
Added in this branch is support for Trusted Foundations secure
firmware, which is what is used on many of the commercial Nvidia Tegra
products that are in the market, including the Nvidia Shield. The
code is local to arch/arm at this time since it's uncertain whether it
will be shared with arm64 longer-term, if needed we will refactor
later.
A couple of new RTC drivers used on ARM boards, merged through our
tree on request by the RTC maintainer.
... plus a bunch of smaller updates across the board, gpio conversions
for davinci, etc"

This patch fix compilation error when driver is compiled
in multi-platform builds.
drivers/built-in.o: In function `msm_otg_link_clk_reset':
./drivers/usb/phy/phy-msm-usb.c:314: undefined reference to `clk_reset'
./drivers/usb/phy/phy-msm-usb.c:318: undefined reference to `clk_reset'
Use platform data supplied reset handlers and adjust error
messages reported when reset sequence fail.
This is an intermediate step before adding support for reset
framework and newer targets.

As the davinci-gpio driver is migrated to use irqdomain
there is no need to pass the irq base for the gpio driver.
This patch removes this variable from davinci_gpio_platform_data
and also the refrences from the machine file.

Pull ARM SoC DT updates from Olof Johansson:
"DT and DT-conversion-related changes for various ARM platforms. Most
of these are to enable various devices on various boards, etc, and not
necessarily worth enumerating.
New boards and systems continue to come in as new devicetree files
that don't require corresponding C changes any more, which is
indicating that the system is starting to work fairly well.
A few things worth pointing out:
* ST Ericsson ux500 platforms have made the major push to move over
to fully support the platform with DT
* Renesas platforms continue their conversion over from legacy
platform devices to DT-based for hardware description"

The R-Car Gen2 SoCs (R8A7790 and R8A7791) have several clocks that are
too custom to be supported in a generic driver. Those clocks can be
divided in two categories:
- Fixed rate clocks with multiplier and divisor set according to boot
mode configuration
- Custom divider clocks with SoC-specific divider values
This driver supports both.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/dt
From Linus Walleij:
Ux500 device tree patches for v3.14, take one:
- Fix up tc3589x bindings so this chip works again.
- Remove SSP platform devices, as we now boot from device tree
exclusively.
- Delete surplus AB8500/DB8500 platform data, not obtained from
the device tree.
- Add DMA config for the MSP devices.
- A series of 21 patches moving pin control config for the
on-chip Nomadik pin controller from the board file
to the device tree, step by step.
- Two patches to the STE DMA40 driver regarding the high-prio
DMA channel so this can be moved to the device tree. Both have
Vinod's ACK.
- Decommission of the non-device tree boot path for the timer
initialization code.
- Deletion of the non-devicetree probe path from the MTU timer
driver, as all platforms using it are now using device tree.
This has Daniel Lezcano's ACK.

Both platforms using the MTU (Nomadik and Ux500) have now been
converted to use device tree exclusively, thus let us delete
this platform data header and make this driver a fully
self-contained DT-only driver.

This decomissions the platform data header (which is no longer
in use after the systems using this driver were switched to
a pure device-tree config path) and merges the result into
the driver file or local driver header.

From Stephen Warren:
ARM: tegra: powergate driver changes
This branch includes all the changes to Tegra's powergate driver for 3.14.
These are separate out, since the Tegra DRM changes for 3.14 rely on the
new APIs introduced here.
A few cleanups and fixes are included, plus additions of Tegra124 SoC
support, and a new API for manipulating Tegra's IO rail deep power down
states.
This branch is based on tag tegra-for-3.14-dmas-resets-rework, in order
to avoid conflicts with the addition of common reset controller support
to the powergate driver.
* tag 'tegra-for-3.14-powergate' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
ARM: tegra: Add IO rail support
ARM: tegra: Special-case the 3D clamps on Tegra124
ARM: tegra: Add Tegra124 powergate support
ARM: tegra: Export tegra_powergate_remove_clamping()
ARM: tegra: Export tegra_powergate_power_off()
ARM: tegra: Rename cpu0 powergate to crail
ARM: tegra: Fix some whitespace oddities

Pull ARM SoC cleanups from Olof Johansson:
"This is the branch where we usually queue up cleanup efforts, moving
drivers out of the architecture directory, header file restructuring,
etc. Sometimes they tangle with new development so it's hard to keep
it strictly to cleanups.
Some of the things included in this branch are:
* Atmel SAMA5 conversion to common clock
* Reset framework conversion for tegra platforms
- Some of this depends on tegra clock driver reworks that are shared
with Mike Turquette's clk tree.
* Tegra DMA refactoring, which are shared branches with the DMA tree.
* Removal of some header files on exynos to prepare for
multiplatform"

Computing the baud rate register value requires knowledge of the
hardware sampling rate. This information is currently encoded in a baud
rate calculation algorithm ID passed through platform data. However, it
can be derived from the port type directly in most cases.
Compute the sampling rate internally in the driver if the baud rate
calculation algorithm ID isn't specified, and allow platforms to
override the sampling rate through platform data in special cases (this
is only required for SCIFA ports on sh7723 and sh7724, the reason needs
to be investigated).

None of the fields is ever set by board code, and both of them are set
in the driver at probe time. Move them out of struct plat_sci_port to
struct sci_port.

Memory and IRQ resources are currently passed to the driver through
platform data. Support passing them through the standard platform
resources mechanism instead. This deprecates platform data resources.

From Stephen Warren:
ARM: tegra: implement common DMA and resets DT bindings
This series converts the Tegra DTs and drivers to use the common/
standard DMA and reset bindings, rather than custom bindings. It also
adds complete documentation for the Tegra clock bindings without
actually changing any binding definitions.
This conversion relies on a few sets of patches in branches from outside
the Tegra tree:
1) A patch to add an DMA channel request API which allows deferred probe
to be implemented.
2) A patch to implement a common part of the of_xlate function for DMA
controllers.
3) Some ASoC patches (which in turn rely on (1) above), which support
deferred probe during DMA channel allocation.
4) The Tegra clock driver changes for 3.14.
Consequently, this branch is based on a merge of all of those external
branches.
In turn, this branch is or will be pulled into a few places that either
rely on features introduced here, or would otherwise conflict with the
patches:
a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid
conflicts.
b) The DRM tree, which introduces new code that relies on the reset
controller framework introduced in this branch, and to avoid
conflicts.

Now that no code uses the custom Tegra module reset API, we can remove
its implementation.

Tegra's clock driver now provides an implementation of the common
reset API (include/linux/reset.h). Use this instead of the old Tegra-
specific API; that will soon be removed.

mmp_pdma.c implements a custom of_xlate() function that is 95% identical
to what Tegra will need. Create a function to implement the common part,
so everyone doesn't just cut/paste the implementation.

This patch adds new at91 pll clock implementation using common clk framework.
The pll clock layout describe the PLLX register layout.
There are four pll clock layouts:
- at91rm9200
- at91sam9g20
- at91sam9g45
- sama5d3
PLL clocks are given characteristics:
- min/max clock source rate
- ranges of valid clock output rates
- values to set in out and icpll fields for each supported output range
These characteristics are checked during rate change to avoid
over/underclocking.
These characteristics are described in atmel's SoC datasheet in
"Electrical Characteristics" paragraph.

This patch moves at91_pmc.h header from machine specific directory
(arch/arm/mach-at91/include/mach/at91_pmc.h) to clk include directory
(include/linux/clk/at91_pmc.h).
We need this to avoid reference to machine specific headers in clk
drivers.

The CCP cannot be hot-plugged so it will either be there
or it won't. Do not allow the driver to stay loaded if the
CCP does not successfully initialize.
Provide stub routines in the ccp.h file that return -ENODEV
if the CCP has not been configured in the build.
