The Cubietruck-plus has a GL830 USB-to-SATA bridge connected to EHCI0,
and a USB3503 HSIC USB 2.0 hub connected to EHCI1. The USB3503's I2C
control interface is not connected.
This patch enables both EHCI controllers, adds a device node for the
USB hub, and includes sunxi-common-regulators.dtsi for the VBUS
regulators. The existing reg_vcc3v3 is dropped as it is also available
in the set of common regulators. Other unused regulators are disabled.

The R_INTC interrupt controller handles the NMI interrupt pin for the
SoC. While there is no documentation or code from the vendor for this
device on the A83T, existing mainline kernel drivers and bindings show
this to be similar to the old Allwinner interrupt controller found on
the A10 SoC, but with only the NMI interrupt wired. Register poking
experiments confirm this.
The device seems to be the same across all recent Allwinner SoCs, apart
from the A20 and A80, which have a separate set of registers to handle
the NMI interrupt. We already have a set of bindings supporting this
on the A31.
Add a device node for it, with an SoC specific compatible.

Convert 'u8 inline' to 'inline u8' to be the same style used by the rest

Miscellanea:
jornada_ssp_reverse is an odd function.
It is declared inline but is also EXPORT_SYMBOL.
It is also apparently only used by jornada720_ssp.c
Likely the EXPORT_SYMBOL could be removed and the function
converted to static.
The addition of static and removal of EXPORT_SYMBOL was not done.

Now that explicitly executed loaders are loaded in the mmap region, we
have more freedom to decide where we position PIE binaries in the
address space to avoid possible collisions with mmap or stack regions.
4MB is chosen here mainly to have parity with x86, where this is the
traditional minimum load location, likely to avoid historically
requiring a 4MB page table entry when only a portion of the first 4MB
would be used (since the NULL address is avoided).
For ARM the position could be 0x8000, the standard ET_EXEC load address,
but that is needlessly close to the NULL address, and anyone running PIE
on 32-bit ARM will have an MMU, so the tight mapping is not needed.

Commit 7dd968163f ("bitmap: bitmap_equal memcmp optimization") was
rather more restrictive than necessary; we can use memcmp() to implement
bitmap_equal() as long as the number of bits can be proved to be a
multiple of 8. And architectures other than s390 may be able to make
good use of this optimisation.

Since commit fcc8487d47 ("uapi: export all headers under uapi

exported, but asm-generic wrappers are still exceptions.
To complete de-coupling the uapi from kernel headers, move generic-y
of exported headers to uapi/asm/Kbuild.
With this change, "make headers_install" will just need to parse
uapi/asm/Kbuild to build up exported headers.

Merge tag 'gpio-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.13 series.
Some administrativa:
I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO
driver coming in through this tree, along with a whole bunch of Exar
8250 fixes. These are ACKed by Greg and also hit drivers/platform/*
where they are ACKed by Andy Shevchenko.
Speaking about drivers/platform/* there is also a bunch of ACPI stuff
coming through that route, again ACKed by Andy.
The MCP23S08 changes are coming in here as well. You already have the
commits in your tree, so this is just a result of sharing an immutable
branch between pin control and GPIO.
Core:
- Export add/remove for lookup tables so that modules can export GPIO
descriptor tables.
- Handle GPIO sleep states: it is now possible to flag that a GPIO
line may loose its state during suspend/resume of the system to
save power. This is used in the Wolfson Micro Arizona driver.
- ACPI-based GPIO was tightened up a lot around the edges.
- Use bitmap_fill() to speed up a loop.
New drivers:
- Exar XRA1403 SPI-based GPIO.
- MVEBU driver now supports Armada 7K and 8K.
- LP87565 PMIC GPIO.
- Renesas R-CAR R8A7743 (RZ/G1M).
- The new IOT2040 8250 serial/GPIO also comes in through this
changeset.
Substantial driver changes:
- Seriously fix the Exar 8250 GPIO portions to work.
- The MCP23S08 was moved out to a pin control driver.
- Convert MEVEBU to use regmap for register access.
- Drop Vulcan support from the Broadcom driver.
- Serious cleanup and improvement of the mockup driver, giving us a
better test coverage.
Misc:
- Lots of janitorial clean up.
- A bunch of documentation fixes"

In this new subsystem we'll try to properly maintain all the generic
code related to dma-mapping, and will further consolidate arch code
into common helpers.
This pull request contains:
- removal of the DMA_ERROR_CODE macro, replacing it with calls
to ->mapping_error so that the dma_map_ops instances are
more self contained and can be shared across architectures (me)
- removal of the ->set_dma_mask method, which duplicates the
->dma_capable one in terms of functionality, but requires more
duplicate code.
- various updates for the coherent dma pool and related arm code
(Vladimir)
- various smaller cleanups (me)

Pull GCC plugin updates from Kees Cook:
"The big part is the randstruct plugin infrastructure.
This is the first of two expected pull requests for randstruct since
there are dependencies in other trees that would be easier to merge
once those have landed. Notably, the IPC allocation refactoring in
-mm, and many trivial merge conflicts across several trees when
applying the __randomize_layout annotation.
As a result, it seemed like I should send this now since it is
relatively self-contained, and once the rest of the trees have landed,
send the annotation patches. I'm expecting the final phase of
randstruct (automatic struct selection) will land for v4.14, but if
its other tree dependencies actually make it for v4.13, I can send
that merge request too.
Summary:
- typo fix in Kconfig (Jean Delvare)
- randstruct infrastructure"
* tag 'gcc-plugins-v4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
ARM: Prepare for randomized task_struct
randstruct: Whitelist NIU struct page overloading
randstruct: Whitelist big_key path struct overloading

gcc-plugins: Add the randstruct plugin
Fix English in description of GCC_PLUGIN_STRUCTLEAK
compiler: Add __designated_init annotation

The main changes this time are from a cleanup series that Krzysztof
Kozłowski did, looking for config options in the defconfig files that
got removed or renamed. He tracked them down to make sure we don't
lose information unintentionally after an update.
Aside from that, there is the usual driver enablement, this time for
davinci, samsung, stm⅗2, bcm2835, qualcomm, at91, imx, mvebu, and omap.

Merge tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC defconfig updates from Arnd Bergmann:
"The main changes this time are from a cleanup series that Krzysztof
Kozłowski did, looking for config options in the defconfig files that
got removed or renamed. He tracked them down to make sure we don't
lose information unintentionally after an update.
Aside from that, there is the usual driver enablement, this time for
davinci, samsung, stm32, bcm2835, qualcomm, at91, imx, mvebu, and
omap"
