Each soc will have to describe the SoC limitation and pin configuration via

This will allow to do not need to touch the C code when adding new SoC if the

Pull MIPS update from Ralf Baechle:
"This is the MIPS update for 3.7.
A fair chunk of them are platform updates to the Cavium Octeon SOC
(which involves machine generated header files of considerable size),
Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx
platforms.
Support for the commercial MIPS simulator MIPSsim has been removed as
MIPS Technologies is shifting away from this product and Qemu is
offering various more powerful platforms. The generic MIPS code can
now also probe for no-execute / write-only TLB features implemented
without the full SmartMIPS extension as permitted by the latest MIPS
processor architecture. Lots of small changes to generic code."

This branch contains updates to OMAP and Marvell platforms (kirkwood,
dove, mvebu) that came in after we had done the big multiplatform merges,
so they were kept separate from the rest, and not separated into the
traditional topics of cleanup/driver/platform features.
For OMAP, the updates are:
- Runtime PM conversions for the GPMC and RNG IP blocks
- Preparation patches for the OMAP common clock framework conversion
- clkdev alias additions required by other drivers
- Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4
- OMAP hwmod code and data improvements
- Preparation patches for the IOMMU runtime PM conversion
- Preparation patches for OMAP4 full-chip retention support
For Kirkwood/Dove/mvebu:
- New driver for "address decoder controller" for mvebu, which
is a piece of hardware that configures addressable devices and
peripherals. First user is the boot rom aperture on armada XP since
it is needed for SMP support.
- New device tree bindings for peripherals such as gpio-fan, iconnect
nand, mv_cesa and the above address decoder controller.
- Some defconfig updates, mostly to enable new DT boards and a few drivers.
- New drivers using the pincontrol subsystem for dove, kirkwood and mvebu
- New clean gpio driver for mvebu

The BCM2835 GPIO module is a combined GPIO controller, (GPIO) interrupt
controller, and pinmux/control device.
Original driver by Simon Arlott.
Rewrite including GPIO chip device by Chris Boot.
Upstreaming changes by Stephen Warren:
* Wrote DT binding documentation.
* Changed brcm,function to an integer to more directly match the
datasheet, and to match brcm,pins being an integer.
* Implemented pull-up/down pin config.
* Removed read-only DT property and related code. The restriction this
implemented are driven by the board, not the GPIO HW block, so don't
really make sense of a HW block binding, were in general incomplete
(since they could only know about the few pins hard-coded into the
Raspberry Pi B board design and not the uncommitted GPIOS), and are
better represented simply by not writing incorrect data into pin
configuration nodes.
* Don't set GPIO_IN function select in gpio_request_enable() to avoid
glitches; defer this to gpio_set_direction(). Consequently, removed
empty bcm2835_pmx_gpio_request_enable().
* Simplified enabled_irq_map[]; make it explicitly 1 entry per bank.
* Lifted use of enabled_irq_map[] outside the per-interrupt loop in
IRQ handler, thus fixing an issue where the code was indexing into
enabled_irq_map[] by intra-bank GPIO ID, not global GPIO ID.
* Removed locking in IRQ handler, since all other code uses
spin_lock_irqsave() and so guarantees it doesn't run concurrently
with the handler.
* Moved duplicated BUILD_BUG_ON()s into probe(). Also check size of
bcm2835_gpio_pins[].
* Remove range-checking from bcm2835_pctl_get_groups_count() since we've
decided to trust the pinctrl core.
* Made bcm2835_pmx_gpio_disable_free() call bcm2835_pinctrl_fsel_set()
directly for simplicity.
* Fixed body of dt_free_map() to match latest dt_node_to_map().
* Removed GPIO ownership check from bcm2835_pmx_enable() since the pinctrl
core owns doing this.
* Made irq_chip and pinctrl_gpio_range .name == MODULE_NAME so it's more
descriptive.
* Simplified remove(); removed call to non-existent
pinctrl_remove_gpio_range(), remove early return on error.
* Don't force gpiochip's base to 0. Set gpio_range.base to gpiochip's
base GPIO number.
* Error-handling cleanups in probe().
* Switched to module_platform_driver() rather than open-coding.
* Made pin, group, and function names lower-case.
* s/broadcom/brcm/ in DT property names.
* s/2708/2835/.
* Fixed a couple minor checkpatch warnings, and other minor cleanup.

Add a new device tree enabled pinctrl and gpiolib driver for Samsung
SoC's. This driver provides a common and extensible framework for all
Samsung SoC's to interface with the pinctrl and gpiolib subsystems. This
driver supports only device tree based instantiation and hence can be
used only on those Samsung platforms that have device tree enabled.
This driver is split into two parts: the pinctrl interface and the gpiolib
interface. The pinctrl interface registers pinctrl devices with the pinctrl
subsystem and gpiolib interface registers gpio chips with the gpiolib
subsystem. The information about the pins, pin groups, pin functions and
gpio chips, which are SoC specific, are parsed from device tree node.

Fix up trivial conflicts in drivers/gpio/gpio-samsung.c that look much
worse than they are: the exonys5 init code was refactored in commit
fd454997d6 ("gpio: samsung: refactor gpiolib init for exynos4/5"), and
then commit f10590c983 ("ARM: EXYNOS: add GPC4 bank instance") added a
new gpio chip define and did tiny updates to the init code.
So the conflict diff looks like hell, but it's actually a fairly simple
change.

With this, five platforms are moving to the relatively new pinctrl
subsystem for their pin management, replacing the older soc specific
in-kernel interfaces with common code.
There is quite a bit of net addition of code for each platform being
added to the pinctrl subsystem. but the payback comes later when adding
new boards can be done by only providing new device trees instead.

The spear/pinctrl branch has hard dependencies on both the
pinctrl branch and the clkdev branch. We merge those here
to fix it up without having to rebase a branch that has
been pulled into other stable branches already.

The driver has mux and config support while the gpio is still
not supported.
For select input setting, the driver will handle it internally
and do not need user to take care of it.
The pinctrl-imx core driver will parse the dts file and dynamically
create the pinmux functions and groups.
Each IMX SoC pinctrl driver should register pins with a pin register map
including mux register and config register and select input map to core
for proper operations.

Define a new binding for the Tegra pin controller, which is capable of
defining all aspects of desired pin multiplexing and pin configuration.
This is all based on the new common pinctrl bindings.
Add Tegra30 binding based on Tegra20 binding.
Add some basic stuff that was missing before:
* How many and what reg property entries must be provided.
* An example.

Also, rename the file using the full compatible value for easier

The core pin controller bindings define:
* The fact that pin controllers expose pin configurations as nodes in
device tree.
* That the bindings for those pin configuration nodes is defined by the
individual pin controller drivers.
* A standardized set of properties for client devices to define numbered
or named pin configuration states, each referring to some number of the
afore-mentioned pin configuration nodes.
* That the bindings for the client devices determines the set of numbered
or named states that must exist.
