8ca302e9c6 ARM: SoC platform updates 
SoC platform changes (arch/arm/mach-*). This merge window, the bulk is
 for a few platforms:
 
 - Andres Färber adds initial support for the Actions Semi S500 (a.k.a.
   'owl') platform, a close relative of the S900 platform he adds for arm64.
 
 - in mach-omap2, we remove more legacy code
 
 - Rockchips gains support for the RV1108 SoC designed for camera
   applications.
 
 - For Atmel, we gain support for MMU-less SoCs (SAME70/V71/S70/V70)
 
 - Minor updates for other platforms, including davinci, s3c64xx,
   prima2, stm32, broadcom nsp, amlogic, pxa, imx and renesas

b39de277b0 spi: Updates for v4.13 
There's only one big change in this release but it's a very big change,
 Geert Uytterhoeven has implemented support for SPI slave mode.  This
 feature has been on the cards since the subsystem was originally merged
 back in the mists of time so it's great that Geert stepped up and
 finally implemented it.
 
  - SPI slave support, together with wholesale renaming of SPI
    controllers from master to controller which went surprisingly
    smoothly.  This is already used with Renesas SoCs and support is in
    the works for i.MX too.
  - New drivers for Meson SPICC and ST STM32

f4dd029ee0 Char/Misc patches for 4.13-rc1 
Here is the "big" char/misc driver patchset for 4.13-rc1.
 
 Lots of stuff in here, a large thunderbolt update, w1 driver header
 reorg, the new mux driver subsystem, google firmware driver updates, and
 a raft of other smaller things.  Full details in the shortlog.
 
 All of these have been in linux-next for a while with the only reported
 issue being a merge problem with this tree and the jc-docs tree in the
 w1 documentation area.  The fix should be obvious for what to do when it
 happens, if not, we can send a follow-up patch for it afterward.

When CONFIG_ARCH_AT91 is enabled, but none of the specific SoC support
is in use, some at91 specific drivers fail to link:

drivers/tty/serial/atmel_serial.o: In function `atmel_serial_suspend':
atmel_serial.c:(.text.atmel_serial_suspend+0x1e): undefined reference to `at91_suspend_entering_slow_clock'

This changes the at91_suspend_entering_slow_clock hack once more, adding
an alternative inline implementation that is used exactly in those cases
that don't provide the normal implementation.

The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch
with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs.
The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII
or RMII. Either of these may connect directly to a host processor or
to an external PHY. The SGMII port may interface to a fiber optic transceiver.

This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.

a90f0e9ebb regulator: Updates for v4.12 
Quite a lot going on with the regulator API for this release, much more
 in the core than in the drivers for a change:
 
  - Fixes for voltage change propagation through dumb power switches.
  - A notification when regulators are enabled.
  - A new settling time property for regulators where the time taken to
    move to a new voltage is not related to the size of the change.
  - Some reorganization of the Arizona drivers in preparation for sharing
    the code with the next generation devices they've been integrated
    with.
  - Support for newer Freescale chips in the Anatop regulator.
  - A new driver for voltage controlled regulators to cope with some
    exciting ChromeOS hardware designs.
  - Support for Rohm BD9571MWV-M and TI TPS65132.

Merge tag 'regulator-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "Quite a lot going on with the regulator API for this release, much
  more in the core than in the drivers for a change:

   - Fixes for voltage change propagation through dumb power switches.

   - A notification when regulators are enabled.

   - A new settling time property for regulators where the time taken to
     move to a new voltage is not related to the size of the change.

   - Some reorganization of the Arizona drivers in preparation for
     sharing the code with the next generation devices they've been
     integrated with.

   - Support for newer Freescale chips in the Anatop regulator.

   - A new driver for voltage controlled regulators to cope with some
     exciting ChromeOS hardware designs.

   - Support for Rohm BD9571MWV-M and TI TPS65132"

140c91b26e watchdog: iTCO_wdt: Add PMC specific noreboot update api 
In some SoCs, setting noreboot bit needs modification to
PMC GC registers. But not all PMC drivers allow other drivers
to memory map their GC region. This could create mem request
conflict in watchdog driver. So this patch adds facility to allow
PMC drivers to pass noreboot update function to watchdog
drivers via platform data.

b62ea4112c video: fbdev: imxfb: support AUS mode 
Some displays require setting AUS mode in the LDCD AUS Mode Control
Register to work with the imxfb driver. Like the value of the Panel
Configuration Register, the AUS mode setting depends on the display
mode.

Allow setting AUS mode from the device tree by adding a boolean
property. Make this property optional to keep the DT ABI stable.
AUS mode can be set only on imx21 and compatible chipsets.

All the supported boards that have OMAP IOMMU devices do support
DT boot only now. So, drop the support for the non-DT legacy-style
devices from the OMAP IOMMU driver. Couple of the fields from the
iommu platform data would no longer be required, so they have also
been cleaned up. The IOMMU platform data is still needed though for
performing reset management properly in a multi-arch environment.

1ec5c1867a This is the bulk of GPIO changes for the v4.11 cycle 
Core changes:
 
 - Augment fwnode_get_named_gpiod() to configure the GPIO pin
   immediately after requesting it like all other APIs do.
   This is a treewide change also updating all users.
 
 - Pass a GPIO label down to gpiod_request() from
   fwnode_get_named_gpiod(). This makes debugfs and the userspace
   ABI correctly reflect the current in-kernel consumer of a pin
   taken using this abstraction. This is a treewide change also
   updating all users.
 
 - Rename devm_get_gpiod_from_child() to
   devm_fwnode_get_gpiod_from_child() to reflect the fact that this
   function is operating on a fwnode object. This is a treewide
   change also updating all users.
 
 - Make it possible to take multiple GPIOs in a single hog of device
   tree hogs.
 
 - The refactorings switching GPIO chips to use the .set_config()
   callback using standard pin control properties and providing
   a backend into the pin control subsystem that were also merged
   into the pin control tree naturally appear here too.
 
 Testing instrumentation:
 
 - A whole slew of cleanups and improvements to the mockup GPIO
   driver. We now have an extended userspace test exercising the
   subsystem, and we can inject interrupts etc from userspace
   to fully test the core GPIO functionality.
 
 New drivers:
 
 - New driver for the Cortina Systems Gemini GPIO controller.
 
 - New driver for the Exar XR17V352/354/358 chips.
 
 - New driver for the ACCES PCI-IDIO-16 PCI GPIO card.
 
 Driver changes:
 
 - RCAR: set the irqchip parent device, add fine-grained runtime
   PM support.
 
 - pca953x: support optional RESET control line on the chip.
 
 - DaVinci: cleanups and simplifications. Add support for multiple
   instances.
 
 - .set_multiple() and naming of lines on more or less all of the
   ISA/PCI GPIO controllers.
 
 - mcp23s08: refactored to use regmap as a first step to further
   rewrites and modernizations.

85adbcd54f spi: Updates for v4.11 
This release is mainly a collection of driver specific updates,
 including a few nice cleanups to make drivers use more core features.
 There
 
  - Automatically use the parent device to allocate DMA buffers if there
    wasn't an explicitly configured device.
  - Fixes for leaks on allocation.
  - A small piece of the start of SPI slave support, a feature that's
    been on the cards for over a decade!

55f0cd3fb9 spi: spi-ep93xx: simplify GPIO chip selects 
This driver requires a GPIO line to be used for the chip select of
each SPI device.

Remove the ep93xx_spi_chip_ops definition from the platform data
and use the spi core GPIO handling for the chip selects.

Fix all the ep93xx platforms that use this driver and remove the
old Documentation.

The pmc_atom driver does not contain any architecture specific
code. It only enables the SoC Power Management Controller driver
for BayTrail and CherryTrail platforms.

Move the pmc_atom driver from arch/x86/platform/atom to
drivers/platform/x86. Also clean-up and reorder include files by
alphabetical order in pmc_atom.h

1141d9d081 clk: x86: Add Atom PMC platform clocks 
The BayTrail and CherryTrail platforms provide platform clocks
through their Power Management Controller (PMC).

The SoC supports up to 6 clocks (PMC_PLT_CLK[0..5]) with a
frequency of either 19.2 MHz (PLL) or 25 MHz (XTAL) for BayTrail
and a frequency of 19.2 MHz (XTAL) for CherryTrail. These clocks
are available for general system use, where appropriate, and each
have Control & Frequency register fields associated with them.

b5cf3fd827 gpio: davinci: Redesign driver to accommodate ngpios in one gpio chip 
The Davinci GPIO driver is implemented to work with one monolithic
Davinci GPIO platform device which may have up to Y(144) gpios.
The Davinci GPIO driver instantiates number of GPIO chips with
max 32 gpio pins per each during initialization and one IRQ domain.
So, the current GPIO's  opjects structure is:

<platform device> Davinci GPIO controller
 |- <gpio0_chip0> ------|
 ...                    |--- irq_domain (hwirq [0..143])
 |- <gpio0_chipN> ------|

Current driver creates one chip for every 32 GPIOs in a controller.
This was a limitation earlier now there is no need for that. Hence
redesigning the driver to create one gpio chip for all the ngpio
in the controller.

|- <gpio0_chip0> ------|--- irq_domain (hwirq [0..143]).
