Tegra DSI support has been fixed to support continuous clock behavior that
the panel used on SHIELD requires, so finally add its device tree node
since it is functional.

The property for enabling external rail control on the AS3722 is
ams,ext-control, not ams,external-control. Since the external rail
control property was previously being ignored, LP1 suspend on these
boards wasn't actually turning the CPU rail off at all.

The device tree node in the SoC file contains only the resources (such
as registers, resets, ...) but none of the lane assignment information
since that's board specific and belongs in the board file.

The pinmux subsystem complained that the nvidia,low-power-mode property
is not supported by the sdio1, sdio3 and gma drive groups. In addition
gma also does not support nvidia,drive-type. Remove these properties so
the pinmux configuration can properly be applied.

This patch adds the device tree to support Toradex Apalis T30, a
computer on module which can be used on different carrier boards.
The module consists of a Tegra 3 SoC, two PMICs, 1 or 2 GB of DDR3L
RAM, eMMC, an LM95245 temperature sensor chip, an i210 resp. i211
gigabit Ethernet controller, an STMPE811 ADC/touch controller as well
as two MCP2515 CAN controllers. Furthermore, there is an SGTL5000 audio
codec which is not yet supported. Anything that is not self contained
on the module is disabled by default.
The device tree for the Evaluation Board includes the modules device
tree and enables the supported peripherals of the carrier board (the
Evaluation Board supports almost all of them).
While at it also add the device tree binding documentation for Apalis
T30.

The Tegra20 fuse driver is the only user of tegra_apb_readl_using_dma().
Therefore we can simply the code by incorporating the APB DMA handling into
the driver directly. tegra_apb_writel_using_dma() is dropped because there
are no users.

Instead of using a simple variable access to get at the Tegra chip ID,
use a function so that we can run additional code. This can be used to
determine where the chip ID is being accessed without being available.
That in turn will be handy for resolving boot sequence dependencies in
order to convert more code to regular initcalls rather than a sequence
fixed by Tegra SoC setup code.

the sample code that the Go coders took, modified, and broke; the
other two implements a workaround that keeps existing Go binaries from
segfaulting at least"

"make vdso_install" installs unstripped versions of the vdso objects
for the benefit of the debugger. This was broken by checkin:
6f121e548f83 x86, vdso: Reimplement vdso.so preparation in build-time C
The filenames are different now, so update the Makefile to cope.
This still installs the 64-bit vdso as vdso64.so. We believe this
will be okay, as the only known user is a patched gdb which is known
to use build-ids, but if it turns out to be a problem we may have to
add a link.

The Go runtime has a buggy vDSO parser that currently segfaults.
This writes an empty SHT_DYNSYM entry that causes Go's runtime to
malfunction by thinking that the vDSO is empty rather than
malfunctioning by running off the end and segfaulting.
This affects x86-64 only as far as we know, so we do not need this for
the i386 and x32 vdsos.

The rule to create the final images uses a zImage.% pattern.
Unfortunately, this also matches the names of the zImage.*.lds linker
scripts, which appear as a dependency of the final images. This somehow
worked when $(srctree) used to be an absolute path, but now the pattern
matches too much. List only the images from $(image-y) as the target of
the rule, to avoid the circular dependency.

Commit 2749a2f26a7c (powerpc/book3s: Fix machine check handling for
unhandled errors) introduced a few ABIv2 issues.
We can maintain ABIv1 and ABIv2 compatibility by branching to the
function rather than the dot symbol.

Pull pwm changes from Thierry Reding:
"The majority of these changes are cleanups and fixes across all
drivers. Redundant error messages are removed and more PWM
controllers set the .can_sleep flag to signal that they can't be used
in atomic context.
Support is added for the Broadcom Kona family of SoCs and the Intel
LPSS driver can now probe PCI devices in addition to ACPI devices.
Upon shutdown, the pwm-backlight driver will now power off the
backlight. It also uses the new descriptor-based GPIO API for more
concise GPIO handling.
A large chunk of these changes also converts platforms to use the
lookup mechanism rather than relying on the global number space to
reference PWM devices. This is largely in preparation for more
unification and cleanups in future patches. Eventually it will allow
the legacy PWM API to be removed"

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull part two of ARM SoC updates from Arnd Bergmann:
"This is a small follow-up to the larger ARM SoC updates merged last
week, almost entirely for the keystone platform.
The main change here is to use the new dma-ranges parsing code that
came in through Russell's ARM tree. This allows the keystone platform
to do cache-coherent DMA and to finally support all the available
physical memory when LPAE is enabled.
Aside from this, the keystone reset driver has been rewritten, and
there is a small bug fix to allow building the orion5x platform again"
