3dbde57ad9 Pin control changes for the v3.11 kernel cycle:
- A large slew of improvements of the Genric pin configuration
   support, and deployment in four different platforms:
   Rockchip, Super-H PFC, ABx500 and TZ1090. Support BIAS_BUS_HOLD,
   get device tree parsing and debugfs support into shape.
 
 - We also have device tree support with generic naming conventions
   for the generic pin configuration.
 
 - Delete the unused and confusing direct pinconf API. Now state
   transitions is *the* way to control pins and multiplexing.
 
 - New drivers for Rockchip, TZ1090, and TZ1090 PDC.
 
 - Two pin control states related to power management are now
   handled in the device core: "sleep" and "idle", removing a lot
   of boilerplate code in drivers. We do not yet know if this is
   the final word for pin PM, but it already make things a lot
   easier to handle.
 
 - Handle sparse GPIO ranges passing a list of disparate pins, and
   utilize these in the new BayTrail (x86 Atom SoC) driver.
 
 - Make the sunxi (AllWinner) driver handle external interrupts.
 
 - Make it possible for pinctrl-single to handle the case where
   several pins are managed by a single register, and augment it to
   handle sleep modes.
 
 - Cleanups and improvements for the abx500 drivers.
 
 - Move Sirf pin control drivers to their own directory, support
   save/restore of context and add support for the SiRFatlas6 SoC.
 
 - PMU muxing for the Dove pinctrl driver.
 
 - Finalization and support for VF610 in the i.MX6 pinctrl driver.
 
 - Smoothen out various Exynos rough edges.
 
 - Generic cleanups of various kinds.

a6e6d863cf regmap: Updates for v3.11
A small but useful set of regmap updates this time around:
 
 - An abstraction for bitfields within a register map contributed by
   Srinivas Kandagatla, allowing drivers to cope more easily when
   hardware designers randomly move things about (mainly when talking
   to things like system controllers).
 
 - Changes from Lars-Peter Clausen to allow the MMIO regmap to be used from
   hard IRQ context.
 
 - Small improvements to the cache infrastructure and performance,
   including a default cache sync operation so now all regmaps can sync
   easily.
 
 There's also a pinctrl driver making use of the new bitfield API, merged
 here for dependency reasons.  There will be a simple add/add conflict
 with the pinctrl tree as a result.

42daabf62b ARM SoC late changes
These are changes that arrived a little late before the merge
 window or that have multiple dependencies on previous branches
 so they did not fit into one of the earlier ones. There
 are 10 branches merged here, a total of 39 non-merge commits.
 Contents are a mixed bag for the above reasons:
 
 * Two new SoC platforms: ST microelectronics stixxxx and
   the TI 'Nspire' graphing calculator. These should have
   been in the 'soc' branch but were a little late
 * Support for the Exynos 5420 variant in mach-exynos,
   which is based on the other exynos branches to avoid
   conflicts.
 * Various small changes for sh-mobile, ux500 and davinci
 * Common clk support for MSM
 
 Conflicts:
 * In Kconfig.debug, various additions trivially conflict,
   the list should be kept in alphabetical order when
   resolving.

0bf6a210a4 ARM SoC driver specific changes
These changes are all driver specific and cross over between arm-soc
 contents and some other subsystem, in these cases cpufreq, crypto,
 dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
 have these changes merged through arm-soc. As we proceed to untangle
 the dependencies between platform code and driver code, the amount of
 changes in this category is fortunately shrinking, for 3.11 we have
 16 branches here and 101 non-merge changesets, the majority of which
 are for the stedma40 dma engine driver used in the ux500 platform.
 Cleaning up that code touches multiple subsystems, but gets rid
 of the dependency in the end.
 
 The mailbox code moved out from mach-omap2 to drivers/mailbox
 is an intermediate step and is still omap specific at the moment.
 Patches exist to generalize the subsystem and add other drivers
 with the same API, but those did not make it for 3.11.
 
 Conflicts:
 * In cpu-db8500.c results from the removal of the u8500_of_init_devices
   function in combination with the split of u8500_auxdata_lookup.
 
 * In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
   we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.

ee1a8d402e ARM SoC device tree changes
These changes from 30 individual branches for the most part update device
 tree files, but there are also a few source code changes that have crept
 in this time, usually in order to atomically move over a driver from
 using hardcoded data to DT probing.
 
 A number of platforms change their DT files to use the C preprocessor,
 which is causing a bit of churn, but that is hopefully only this once.
 
 There are a few conflicts with the other branches unfortunately:
 
 * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
   from multiple branches. Need to be careful to have the right
   set of closing braces as git gets this one wrong.
 
 * In kirkwood.dtsi, one 'ranges' line got split into two lines, while
   another line got added. Order of the lines does not matter.
 
 * in sama5d3.dtsi, some cleanup was merged the wrong way, causing
   a bogus conflict. We want the 'dmas' and 'dma-names' properties
   to get added here.
 
 * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
 
 * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

5c75acdcae pinctrl: st: fix return value check
In case of error, the function pinctrl_register() returns
NULL not ERR_PTR(). The IS_ERR() test in the return value
check should be replaced with NULL test.
The function syscon_regmap_lookup_by_phandle() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

701016c0cb pinctrl: st: Add pinctrl and pinconf support.
This patch add pinctrl support to ST SoCs.

About hardware:
ST Set-Top-Box parts have two blocks called PIO and PIO-mux which handle
pin configurations.

Each multi-function pin is controlled, driven and routed through the PIO
multiplexing block. Each pin supports GPIO functionality (ALT0) and
multiple alternate functions(ALT1 - ALTx) that directly connect the pin
to different hardware blocks. When a pin is in GPIO mode, Output Enable
(OE), Open Drain(OD), and Pull Up (PU) are driven by the related PIO
block. Otherwise the PIO multiplexing block configures these parameters
and retiming the signal.

About driver:
This pinctrl driver manages both PIO and PIO-mux block using pinctrl,
pinconf, pinmux, gpio subsystems. All the pinctrl related config
information can only come from device trees.

5b81d55c4c pinctrl: remove bindings for pinconf options needing more thought
Some options currently take arguments in unspecified driver-specific units.
As pointed out by Stephen Warren, driver specific values should not be part
of generic devicetree bindings describing the hardware.

Therefore remove the critical bindings again, before they become part of
an official release.

256aeb6487 pinctrl: set unit for debounce time pinconfig to usec
Currently the debounce time pinconfig option uses an unspecified
"time units" unit. As pinconfig options should use SI units and a
real unit is also necessary for generic dt bindings, change it
to usec. Currently no driver is using the generic pinconfig option
for this, so the unit change is safe to do.

ad42fc6c84 pinctrl: rip out the direct pinconf API
From the inception ot the pin config API there has been the
possibility to get a handle at a pin directly and configure
its electrical characteristics. For this reason we had:

int pin_config_get(const char *dev_name, const char *name,
               unsigned long *config);
int pin_config_set(const char *dev_name, const char *name,
               unsigned long config);
int pin_config_group_get(const char *dev_name,
               const char *pin_group,
               unsigned long *config);
int pin_config_group_set(const char *dev_name,
               const char *pin_group,
               unsigned long config);

After the introduction of the pin control states that will
control pins associated with devices, and its subsequent
introduction to the device core, as well as the
introduction of pin control hogs that can set up states on
boot and optionally also at sleep, this direct pin control
API is a thing of the past.

As could be expected, it has zero in-kernel users.
Let's delete this API and make our world simpler.

b58f0273f0 pinctrl-tz1090-pdc: add TZ1090 PDC pinctrl driver
Add a pin control driver for the TZ1090's low power pins via the
powerdown controller SOC_GPIO_CONTROL registers.

These pins have individually controlled pull-up, and group controlled
schmitt, slew-rate, drive-strength, and power-on-start (pos).

The pdc_gpio0 and pdc_gpio1 pins can also be muxed onto the
ir_mod_stable_out and ir_mod_power_out functions respectively. If no
function is set they remain in GPIO mode. These muxes can be overridden
by requesting them as GPIOs.

Add support for gpio on Intel BayTrail platforms. BayTrail supports 3 banks
of gpios called SCORE, NCORE ans SUS with 102, 28 and 44 gpio pins.
Supports gpio interrupts and ACPI gpio events

Pins may be muxed to alternate function instead of gpio by firmware.
This driver does not touch the pin muxing and expect firmare
to set pin muxing and pullup/down properties properly.
