With every SoC always providing its own get/set callbacks, we can now
remove the generic ones, remove the obsolete base address, and always
use the provided callbacks.

The way that mvebu pinctrl is designed, requesting mpp registers
in common pinctrl driver does not allow SoC specific drivers to
access this resource.
Move resource allocation in each SoC pinctrl driver and enable
already provided mpp_{set,get} callbacks.

The only valuable information a special callback can derive from
mvebu_mpp_ctrl passed to it, is the pin id. Instead of passing
the struct, pass the pid directly.

We treat unnamed controls as generic mvebu mpp register controls but
we identify them by not being special controls. Flip the logic and
use the name pointer as identification instead. While at it, add some
comments explaining the not so obvious treatment.

pinctrl-mvebu allows SoCs to pass unnamed controls that will get an
auto-generated name of "mpp<PIN#>". Currently, we are allocating name
buffers on a per-control basis while looping over passed controls.
This counts the total number of unnamed controls and allocates a
global name buffer instead. The new buffer is then used while assigning
controls to pinctrl groups later.

On systems which were not booted using DT it is entirely unsurprising that
device nodes don't have any DT information and this is going to happen for
every single device in the system. Make pinctrl be less chatty about this

and RX frame sync.

For some silicons, the pin configuration register can control
the output of the pin when the pad including the pin enter
low power mode.
For example, the pin can be "Drive 1", "Drive 0", "Float" when
the pad including the pin enter low power mode.
It is very useful when you want to control the power leakeage
when the SOC enter low power mode, and can save more power for
the low power mode.

ST pin controller does not have hardware support for detecting edge
triggered interrupts, It only has level triggering support.
This patch attempts to fake up edge triggers from hw level trigger
support in software. With this facility now the gpios can be easily used
for keypads, otherwise it would be difficult for drivers like keypads to
work with level trigger interrupts.

This patch add interrupt support to the pincontroller driver.
ST Pincontroller GPIO bank can have one of the two possible types of
interrupt-wirings.
First type is via irqmux, single interrupt is used by multiple gpio
banks. This reduces number of overall interrupts numbers required. All
these banks belong to a single pincontroller.
_________
| |----> [gpio-bank (n) ]
| |----> [gpio-bank (n + 1)]
[irqN]-- | irq-mux |----> [gpio-bank (n + 2)]
| |----> [gpio-bank (... )]
|_________|----> [gpio-bank (n + 7)]
Second type has a dedicated interrupt per gpio bank.
[irqN]----> [gpio-bank (n)]

Pull ARM SoC fixes from from Olof Johansson:
"A collection of fixes for ARM platforms. A little large due to us
missing to do one last week, but there's nothing in particular here
that is in itself large and scary.
Mostly a handful of smaller fixes all over the place. The majority is
made up of fixes for OMAP, but there are a few for others as well. In
particular, there was a decision to rename a binding for the Broadcom
pinctrl block that we need to go in before the final release since we
then treat it as ABI"

On tha Allwinner A20 SoC, the external interrupts on the pin controller
device are connected to the GIC. Without chained_irq_{enter, exit},
external GPIO interrupts, such as used by mmc core card detect, cause
the system to hang.
This issue was first encountered during my attempt to get out-of-band
interrupts for WiFi on the Cubietruck working. With David's new series
of sunci-mci using mmc slot-gpio for (GPIO interrupt based) card
detection, removing the SD card also causes my Cubietruck to hang. This
problem should extend to all Allwinner A20 based boards.
With this fix, the system no longer hangs when I remove or insert the
SD card. /proc/interrupts show that the interrupt has correctly fired.
However the system still does not detect card removal/insertion. I
believe this is another unrelated issue.

Commit c420619 "pinctrl: pinconf: remove checks on ops->pin_config_get"
removed the check on (ops != NULL) when performing pinconf_pins_show() or
pinconf_groups_show(). As these entries are always enabled, even if
pinconf is not supported, reading will result in an oops due to NULL
ops.
Instead of checking for ops, remove the corresponding debugfs entries if
pinconf and/or pinmux are not implemented.
Tested on OMAP3 (pinctrl-single).

We have few fedora bug reports about list corruption on pinctrl,
for example:
https://bugzilla.redhat.com/show_bug.cgi?id=1051918
Most likely corruption happen due lack of protection of pinctrl_list
when adding new nodes to it. Patch corrects that.

Due to an assumption in the VT8500 pinctrl driver, the value passed
from devicetree for 'wm,pull' was not explicitly translated before
being passed to pinconf.
Since v3.10, changes to 'enum pin_config_param', PIN_CONFIG_BIAS_PULL_(UP/DOWN)
no longer map 1-to-1 with the expected values in devicetree.
This patch adds a small translation between the devicetree values (0..2)
and the enum pin_config_param equivalent values.
