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.
Conflicts:
* In cpu-db8500.c results from the removal of the u8500_of_init_devices
function in combination with the split of u8500_auxdata_lookup.
* In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.

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.
Conflicts:
* asm/glue-proc.h has one CPU type getting added that conflicts
with another addition in 3.10-rc7
* Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

Here's the large staging tree merge for 3.11-rc1
Huge thing here is the Lustre client code. Unfortunatly, due to it not
building properly on a wide variety of different architectures (this was
production code???), it is currently disabled from the build so as to
not annoy people.
Other than Lustre, there are loads of comedi patches, working to clean
up that subsystem, iio updates and new drivers, and a load of cleanups
from the OPW applicants in their quest to get a summer internship.
All of these have been in the linux-next releases for a while (hence the

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.

From Sekhar Nori:
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.

The OMAP mailbox platform driver code has been cleaned up to
remove the dependencies with soc.h in preparation for moving
the mailbox code to drivers folder.
The code relied on cpu_is_xxx/soc_is_xxx macros previously to
pick the the right set of mailbox devices and register with the
mailbox driver. This data is now represented in a concise format
and moved to the respective omap_hwmod data files and published
to the driver through the platform data.

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.

Currently the driver hard-codes USBPCTRL0 register to 0. It is wrong since this
register contains board-specific USB ports configuration and so its value should
be somehow passed via the platform data. Add the global header file containing
'struct rcar_phy_platform_data' consisting of the various bit fields describing
USB ports' pin configuration.

Pins are numbered in the R-Car family documentation using a bank number
and a pin number in the bank. As the Linux pin number space is linear,
we need to flatten this by multiplying the bank number by 32 and adding
the pin number. The resulting number bear no directly visible
relationship to the documentation, making it error-prone.
Add a RCAR_GP_PIN macro to convert from the documentation pin number
space to the linear Linux space.

At this moment in time the memcpy channels which can be used by the D40
are fixed, as each supported platform in Mainline uses the same ones.
However, platforms do exist which don't follow this convention, so
these will need to be tailored. Fortunately, these platforms will be DT
only, so this change has very little impact on platform data.

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.

Move this knowledge into the driver so we can relinquish the burden from

ACPI / LPSS: register clock device for Lynxpoint DMA properly

DMA addresses are now passed as part of the dmaengine API by invoking

driver to look them up in a table provided by platform data. This

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.

Devices which utilise DMA use the same device numbers for transmitting
and receiving. In this patch we encode the source and destination
information into one single attribute. We can subsequently exploit the
direction attribute to see which of the transfer directions are being
described. This also lessens the burden on platform data.

The DMA controller in Lynxpoint is enumerated as a regular ACPI device now. To
work properly it is using the LPSS root clock as a functional clock. That's why
we have to register the clock device accordingly to the ACPI ID of the DMA
controller. The acpi_lpss.c module is responsible to do the job.
This patch also removes hardcoded name of the DMA device in clk-lpt.c and the
name of the root clock in acpi_lpss.c.

These patches are all for Renesas shmobile, and depend on the earlier
pinctrl updates. Remarkably, this adds support for three new SoCs:
r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is
for pinctrl (using the new subsystem) and for clocks (not yet using the
common clock subsystem). The latter will have to get converted in one
of the upcoming releases, but shmobile is not ready for that yet.
The series also contains Renesas shmobile board changes, adding one
board file for each of the three new SoCs. These boards are using a
mix of classic and device-tree based probing, as there is still a lot of
infrastructure in shmobile that has not been converted to DT yet. Once
those are resolved to the degree that no board specific setup code is
needed, they can get folded into the respective SoC setup files.

This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem
specific interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into
platform specific interface, or to get called from platform specific
code, as long as all information about the hardware is provided
through a device tree.
Most of the drivers we touch this time are for clocksource. Since
now most of them are part of drivers/clocksource, I expect that we
won't have to touch these again from arm-soc and can let the
clocksource maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the
merge conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface
for taking devices on the SoC out of reset or back into reset.
Patches to use this interface on i.MX follow later in this merge
window, and we are going to have other platforms (at least tegra
and sirf) get converted in 3.11. This will let us get rid of
platform specific callbacks in a number of platform independent

More multiplatform enablement for ARM platforms. The ones converted in
this branch are:
- bcm2835
- cns3xxx
- sirf
- nomadik
- msx
- spear
- tegra
- ux500
We're getting close to having most of them converted!
One of the larger platforms remaining is Samsung Exynos, and there are
a bunch of supporting patches in this merge window for it. There was a
patch in this branch to a early version of multiplatform conversion,
but it ended up being reverted due to need of more bake time. The
revert commit is part of the branch since it would have required
rebasing multiple dependent branches and they were stable by then.
