The PPC_OF is a ppc specific option which is used to mean that the
firmware device tree access functions are available. Since all the
ppc platforms have a device tree, it is aways set to 'y' for ppc.
So it makes no sense to keep a such option in the current kernel.
Replace it with PPC.

Intel Quark X1000 provides a total of 16 GPIOs. The GPIOs are split between
the legacy I/O bridge and the GPIO controller.
GPIO-SCH is the GPIO pins on legacy bridge for Intel Quark SoC.
Intel Quark X1000 has 2 GPIOs powered by the core power well and 6 from
the suspend power well.
This piece of work is derived from Dan O'Donovan's initial work for Quark
X1000 enabling.

Pull take two of the GPIO updates:
"Same stuff as last time, now with a fixup patch for the previous
compile error plus I ran a few extra rounds of compile-testing.
This is the bulk of GPIO changes for the v3.19 series:
- A new API that allows setting more than one GPIO at the time. This
is implemented for the new descriptor-based API only and makes it
possible to e.g. toggle a clock and data line at the same time, if
the hardware can do this with a single register write. Both
consumers and drivers need new calls, and the core will fall back
to driving individual lines where needed. Implemented for the
MPC8xxx driver initially
- Patched the mdio-mux-gpio and the serial mctrl driver that drives
modems to use the new multiple-setting API to set several signals
simultaneously
- Get rid of the global GPIO descriptor array, and instead allocate
descriptors dynamically for each GPIO on a certain GPIO chip. This
moves us closer to getting rid of the limitation of using the
global, static GPIO numberspace
- New driver and device tree bindings for 74xx ICs
- New driver and device tree bindings for the VF610 Vybrid
- Support the RCAR r8a7793 and r8a7794
- Guidelines for GPIO device tree bindings trying to get things a bit
more strict with the advent of combined device properties
- Suspend/resume support for the MVEBU driver
- A slew of minor fixes and improvements"

Whereas the DWAPB driver does not really depend on the ARM
architecture, it uses [readl|writel]_relaxed() not found on
arch such as Blackfin, so restrict this to ARM until there is
another architecture that can make use of it.
It is also using the of_node of the gpiochip, so fix this
too by requiring OF_GPIO.

Pull GPIO update from Linus Walleij:
"This is the bulk of GPIO changes for the v3.17 development cycle, and
this time we got a lot of action going on and it will continue:
- The core GPIO library implementation has been split up in three
different files:
- gpiolib.c for the latest and greatest and shiny GPIO library code
using GPIO descriptors only
- gpiolib-legacy.c for the old integer number space API that we are
phasing out gradually
- gpiolib-sysfs.c for the sysfs interface that we are not entirely
happy with, but has to live on for ABI compatibility
- Add a flags argument to *gpiod_get* functions, with some
backward-compatibility macros to ease transitions. We should have
had the flags there from the beginning it seems, now we need to
clean up the mess. There is a plan on how to move forward here
devised by Alexandre Courbot and Mark Brown
- Split off a special <linux/gpio/machine.h> header for the board
gpio table registration, as per example from the regulator
subsystem
- Start to kill off the return value from gpiochip_remove() by
removing the __must_check attribute and removing all checks inside
the drivers/gpio directory. The rationale is: well what were we
supposed to do if there is an error code? Not much: print an error
message. And gpiolib already does that. So make this function
return void eventually
- Some cleanups of hairy gpiolib code, make some functions not to be
used outside the library private and make sure they are not
exported, remove gpiod_lock/unlock_as_irq() as the existing
function is for driver-internal use and fine as it is, delete
gpio_ensure_requested() as it is not meaningful anymore
- Support the GPIOF_ACTIVE_LOW flag from gpio_request_one() function
calls, which is logical since this is already supported when
referencing GPIOs from e.g. device trees
- Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use the gpiolib
irqchip helpers cutting down on GPIO irqchip boilerplate a bit more
- New driver for the Zynq GPIO block
- The usual incremental improvements around a bunch of drivers
- Janitorial syntactic and semantic cleanups by Jingoo Han, and
Rickard Strandqvist especially"

Commit 4df42de9d3e "gpio: omap: add a GPIO_OMAP option instead of using
ARCH_OMAP" made it possible to build OMAP kernels without the GPIO driver,
which at least on OMAP2 and OMAP3 causes build errors because of functions
used by the platform power management code:
arch/arm/mach-omap2/built-in.o: In function `omap_sram_idle':
arch/arm/mach-omap2/pm24xx.c:129: undefined reference to `omap2_gpio_prepare_for_idle'
arch/arm/mach-omap2/pm24xx.c:129: undefined reference to `omap2_gpio_resume_after_idle'
We presumably always want the GPIO driver on OMAP, so this adds a slightly
broader dependency and only allows disabling the driver only when no
OMAP2PLUS platform is selected.
However, it seems entirely reasonable to include the driver in build tests
on other platforms, so we should also allow building it for COMPILE_TEST
builds and select the required GENERIC_IRQ_CHIP that may not already be
enabled on other platforms.

The ARCH_OMAP config option was used to built the GPIO OMAP
driver but this is not consistent with the rest of the GPIO
drivers that have their own Kconfig option.
Also, this make it harder to add dependencies or reverse
dependencies (i.e: select) since that would mean touching the
sub-arch config option.
So is better to add a boolean Kconfig option for this driver
that defaults to true if ARCH_OMAP is enabled.

This provides a function gpiochip_irqchip_add() to set
up an irqchip for a GPIO controller, and a function
gpiochip_set_chained_irqchip() to chain it to a parent
irqchip.
Most GPIOs are of the type where a number of lines form
a cascaded interrupt controller chained onto
the primary system interrupt controller (or further down the
chain) so let's add this helper and factor the code to
request the lines to be used as IRQs, the .to_irq() function
and the irqdomain into the core as well.

v9: - cleanup in dt bindings doc
- use of_get_child_count()
v8: - remove socfpga.dtsi changes
- minor cleanup in devicetree documentation
v7: - use irq_generic_chip
- support one irq per gpio line or one irq for many
- s/bank/port/ and other cleanup
v6: - (atull) squash the set of patches
- use linear irq domain
- build fixes. Original driver was reviewed on v3.2.
- Fix setting irq edge type for 'rising' and 'both'.
- Support as a loadable module.
- Use bgpio_chip's spinlock during register access.
- Clean up register names to match spec
- s/bank/port/ because register names use the word 'port'
- s/nr-gpio/nr-gpios/
- don't get/put the of_node
- remove signoffs/acked-by's because of changes
- other cleanup
v5: - handle sparse bank population correctly
v3: - depend on rather than select IRQ_DOMAIN
- split IRQ support into a separate patch
v2: - use Rob Herring's irqdomain in generic irq chip patches
- use reg property to indicate bank index
- support irqs on both edges based on LinusW's u300 driver

There is no point in displaying the TS5500-specific driver entries if
TS5500 board support itself isn't enabled.

Merge "qcom driver changes for v3.15" from Kumar Gala:
We've split Qualcomm MSM support into legacy and multiplatform. These
drivers are only relevant on the multiplatform supported SoCs so switch the
Kconfig depends to ARCH_QCOM.
* tag 'qcom-drivers-for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/galak/linux-qcom:
gpio: msm: switch Kconfig to ARCH_QCOM depends
hwrng: msm: switch Kconfig to ARCH_QCOM depends
power: reset: msm - switch Kconfig to ARCH_QCOM depends
drm/msm: drop ARCH_MSM Kconfig depend
tty: serial: msm: Enable building msm_serial for ARCH_QCOM
