3ce0d7eba0 sh-pfc: Pass the pin number down to the port function macro
The PORT_1 macro invokes a macro passed as a parameter. Pass the pin
number down to that macro at the bottom of the call stack. This will be
used to compute the pin ranges automatically.

7cbb0e55e2 sh-pfc: Don't duplicate argument to PINMUX_GPIO macro
The PINMUX_GPIO macro takes a port name and a data mark, respectively of
the form GPIO_name and name_DATA. Modify the macro to take the name as a
single argument and derive the port name and data mark from it.

757b055a65 sh-pfc: Rename gpio arguments to be consistent with the rest of the code
The gpio_get_data_reg() and gpio_setup_data_reg() functions both take an

a1a3580cb3 sh-pfc: Don't overallocate memory for the GPIO chip pins array
The GPIO driver uses an array of sh_pfc_gpio_pin structures to store
per-GPIO pin data. The array size is miscomputed at allocation time by
using the number of the last pin instead of the number of pins. When the
pin space contains holes this leads to memory overallocation. Fix it.

f33334978a pinctrl: Remove duplicate code in pinctrl_pm_select_state functions
There's no need to duplicate essentially the same functions. Let's
introduce static int pinctrl_pm_select_state() and make the other
related functions call that.

This allows us to add support later on for multiple active states,
and more optimized dynamic remuxing.

Note that we still need to export the various pinctrl_pm_select
functions as we want to keep struct pinctrl_state private to the
pinctrl code, and cannot replace those with inline functions.

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

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.

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.

Defining a pinconf_generic_parse_dt_config() on !CONFIG_OF would have
been possible as well, but would have resulted in a larger code size on
!CONFIG_OF platforms (such as arch/sh).

Add a new PIN_CONFIG_BIAS_BUS_HOLD pin configuration for a bus holder
pin mode (also known as bus keeper, or repeater). This is a weak latch
which drives the last value on a tristate bus. Another device on the bus
can drive the bus high or low before going tristate to change the value
driven by the pin.

44d5f7bbea pinctrl: sink pinctrldev_list_mutex
The pinctrldev_list_mutex is sinked into the functions that
actually traverse the list and lock it there. The code makes
much more sense in this way. All the callers are in
non-performance critical paths and the code is way more
readable this way.

Also refactor the function get_pinctrl_dev_from_devname() to
follow the design pattern of get_pinctrl_dev_from_of_node()
which is slightly simpler.

3370dc916c pinctrl:sirf:re-arch and add support for new SiRFatlas6 SoC
atlas6 is a SoC very similar with primaII, the register layput of
pinctrl is same, but the pads, groups and functions of atlas6 have
different layout with prima2, this patch
1. pull the definition of pads, groups and functions out of the
pinctrl-sirf driver,and put them into soc-specific files
2. add pads, groups and functions tables for atlas6
3. let pads, groups and functions tables become the config data of
   the related dt compatible node, so the pinctrl-sirf can support
   all SiRF SoCs with the config data as private data.

In this patch,we create a sirf dir, and let
the old drivers/pinctrl/pinctrl-sirf.c =
        drivers/pinctrl/sirf/pinctrl-prima2.c +
        drivers/pinctrl/sirf/pinctrl-sirf.c

drivers/pinctrl/sirf/pinctrl-atlas6.c is a newly created file for the
pin layout of atlas6.

ea770ad2ec sh-pfc: sh73a0: Add VCCQ MC0 regulator
The sh73a0 has an internal power gate on the VCCQ power supply for the
SDHI0 device that is controlled (for some strange reason) by a bit in a
PFC register. This feature should be exposed as a regulator.

As the same register is also used for pin control purposes there is no
way to achieve atomic read/write sequences with a separate regulator
driver. We thus need to implement the regulator here.

b79839024f sh-pfc: r8a7740: Hardcode the LCDC0 output
The r8a7740 has two LCDC units and two sets of LCDC output signals. By
default LCDC0 is routed to the LCD0 signals, and LCDC1 to the LCD1
signals. However, LCDC1 can be routed to the LCD0 signals by setting bit
MSEL6 in MSEL3CR (the LCD0 signals are further pinmuxed the usual way).

This could be configured by duplicating the LCD0 pin groups for LCDC1.
However, this would unnecessarily complicate the LCD pin groups, as no
r8a7740 board supported in mainline use such a configuration. Hardcode
the MSEL3CR MSEL6 bit to 0 for now.
