This fix allows to correctly select default and
alternate pin mode.
By default for all ABx500 family chip, pin default
mode is selected by clearing corresponding bit in
GPIOSELx register except for pins which support
alternate function, in this case, corresponding bit
must be set.
But, due to an unlogical hardware implementation,
for one particular pin (GPIO11) reverse setting
must be done. For that, update the alternate function
array by declaring that this pin supports alternate
function.
Same issue has been fixed in pinctrl-ab8505.c

As Stephen Warren pointed out, pinctrl_free_setting() was called instead
of pinmux_disable_setting() on error.
In this error code, we want to call pinmux_disable_setting() where
pinmux_enable_setting() was called.
And when pinconf_apply_setting() was called, we can't do much to undo
the pin muxing (the closest thing I can think about for "unmuxing" a pin
is muxing it as GPIO input).

Since gpio driver could create gpio range in DTS, it could invoke
pinctrl_request_gpio(). In the pinctrl-single driver, it needs to
configure pins with gpio function mode.
A new gpio function range should be created in DTS file in below.
pinctrl-single,gpio-range = <phandle pin_offset nr_pins gpio_func>;
range: gpio-range {
#pinctrl-single,gpio-range-cells = <3>;
};
The gpio-ranges property is used in gpio driver and the
pinctrl-single,gpio-range property is used in pinctrl-single driver.
1. gpio-ranges is used for gpio driver in below.
gpio-ranges = <phandle gpio_offset_in_chip pin_offset nr_pins>
gpio-ranges = < &pmx0 0 89 1 &pmx0 1 89 1 &pmx0 2 90 1
&pmx0 3 90 1 &pmx0 4 91 1 &pmx0 5 92 1>;
2. gpio driver could get pin offset from gpio-ranges property.
pinctrl-single driver could get gpio function mode from gpio_func
that is stored in @gpiofuncs list in struct pcs_device.
This new pinctrl-single,gpio-range is used as complement for
gpio-ranges property in gpio driver.

pinctrl_get_device_gpio_range() only checks whether a certain GPIO pin
is in gpio range. But maybe some GPIO pins don't have back-end pinctrl
interface, it means that these pins are always configured as GPIO
function. For example, gpio159 isn't related to back-end pinctrl device
in Hi3620 while other GPIO pins are related to back-end pinctrl device.
Append pinctrl_ready_for_gpio_range() that is used to check whether
pinctrl device with GPIO range is ready. This function will be called
after pinctrl_get_device_gpio_range() fails.
If pinctrl device with GPIO range is found, it means that pinctrl device
is already launched and a certain GPIO pin just don't have back-end pinctrl
interface. Then pinctrl_request_gpio() shouldn't return -EPROBE_DEFER in
this case.

reason for this is tight dependencies (that will now mostly be broken)

Pull non-critical ARM SoC bug fixes from Arnd Bergmann:
"Bug fixes that did not make it into v3.8, mostly because they were not
considered important enough, and in some cases because bugs only show
up in combination with other patches destined for 3.9. This includes
a few larger patches for GPIO on the Marvell PXA platform and a lot of
Samsung specific bug fixes, as well as a series from Arnd to fix older
build warnings."

Here is the big driver core merge for 3.9-rc1
There are two major series here, both of which touch lots of drivers all
over the kernel, and will cause you some merge conflicts:
- add a new function called devm_ioremap_resource() to properly be
able to check return values.
- remove CONFIG_EXPERIMENTAL
If you need me to provide a merged tree to handle these resolutions,
please let me know.
Other than those patches, there's not much here, some minor fixes and
updates.

- Grabbing of default pinctrl handles from the device core.
These are the hunks hitting drivers/base. All is ACKed by
Greg, after a long discussion about different alternatives.
- Some stuff also touches the MFD and ARM SoC trees, this has
been coordinated and ACKed.
- New drivers for:
- The Tegra 114 sub-SoC
- Allwinner sunxi
- New ABx500 driver and sub-SoC drivers for AB8500,
AB8505, AB9540 and AB8540.
- Make it possible for hogged pins to enter a sleep mode,
and make it possible for drivers to control that mode.
- Various clean-up, extensions and device tree support to
various pin controllers.

This update adds a debugfs interface to modify a pin configuration
for a given state in the pinctrl map. This allows to modify the
configuration for a non-active state, typically sleep state.
This configuration is not applied right away, but only when the state
will be entered.
This solution is mandated for us by HW validation: in order
to test and verify several pin configurations during sleep without
recompiling the software.
