The bias-pull-* options use values > 0 to indicate that the pull should
be activated and optionally also indicate the strength of the pull.
Therefore use an default value of 1 for these options.
Split the low-power-mode option into low-power-enable and -disable.
Update the documentation to describe the param arguments better.

Add the f2fs_remount function call which will be used
during the filesystem remounting. This function
will help us to change the mount options specific to
f2fs.
Also modify the f2fs background_gc mount option, which
will allow the user to dynamically trun on/off the
garbage collection in f2fs based on the background_gc
value. If background_gc=on, Garbage collection will
be turned off & if background_gc=off, Garbage collection
will be truned on.
By default the garbage collection is on in f2fs.
Change Log:
v2: Incorporated the review comments by Gu Zheng.
Removing the restore part for VFS flags
Updating comments with proper flag conditions
Display GC background option as ON/OFF
Revised conditions to stop GC in case of remount
v1: Initial changes for adding remount_fs callback
support.

This adds a device tree node for the U300 system controller
and remaps this dynamically instead of using hard-coded
virtual addresses. The board power set-up code is altered
to fetch a reference to the syscon using ampersand <&syscon>
notation. This way of passing a pointer to the syscon will
also be used by the clocks.

The WEIM(Wireless External Interface Module) works like a bus.
You can attach many different devices on it, such as NOR, onenand.
In the case of i.MX6q-sabreauto, the NOR is connected to WEIM.
This patch also adds the devicetree binding document.
The driver only works when the devicetree is enabled.

With the commit 7f217794f (mmc: dt: Consolidate DT bindings),
the device tree properties used by various device drivers
for SD/MMC host controllers were standardized. One of the changes
was that the property "fsl,card-wired", previously used by the
Freescale driver, was replaced with "non-removable". Fix the example
documentation regarding this.

This driver adds support the Cortex-A9 based SoCs from Rockchip,
so at least the RK2928, RK3066 (a and b) and RK3188.
Earlier Rockchip SoCs seem to use similar mechanics for gpio
handling so should be supportable with relative small changes.
Pull handling on the rk3188 is currently a stub, due to it being
a bit different to the earlier SoCs.
Pinmuxing as well as gpio (and interrupt-) handling tested on
a rk3066a based machine.

pinconf_generic_parse_dt_config() takes a node as input and generates an
array of generic pinconfig values from the properties of this node.
As I couldn't find a mechanism to count the number of properties of a node
the function uses internally an array to accept one of parameter and copies
the real present options to a smaller variable at its end.

Add support to configure multiple pins in each register, existing
implementation added by [1] does not support full fledge multiple pin
configuration in single register, reports a pin clash when different
modules configure different bits of same register. The issue reported

With pinctrl-single,bits-per-mux property specified, use function-mask
property to find out number pins to configure. Allocate and register
pin control functions based sub mask.
Tested on da850/omap-l138 EVM.
does not support variable submask for pins.
does not support pinconf.

This registers the memory ranges for I/O, non-prefetched and
prefetched memory and configuration space for the PCIv3 bridge
and let us fetch these basic memory resources from the device
tree in the device tree boot path. Remove the stepping stone
platform device. This is an either/or approach - the platform
data path is mutually exclusive to the plain platform data
path and provided addresses from the device tree have to be
correct.
This adds the interrupt-map property to the PCIv3 DTS file
and makes the bridge obtain mappings from the device tree.

ARM: tegra: device tree updates
This branch contains all device tree updates for Tegra boards.
The changes are:
* Converted all DT files to use the C pre-processor, to support the use
of named constants. This included use of defines for GPIO, IRQ, and
clock constants.
* Enabling new features such as:
- SPI on Dalmore.
- Audio on Dalmore and Beaver.
- gpio-leds on Beaver.
- Power-supply/batter linkage on Dalmore.
* A minor fix to the RAM size node on Beaver.
It is based on previous pull request tegra-for-3.11-deps-for-usb
followed by a merge of tegra-for-3.11-deps-for-clk.
