8bd6f53af5 This is a patch series that updates imx-weim bus driver to have it
support more i.MX SoCs.  Because there is no maintainer for
 drivers/bus so far, I'm forwarding it through IMX tree for 3.12 merge
 window.

0b1252784b bus: mvebu-mbus: Add devicetree binding
Introduce the devicetree binding for the mvebu MBus driver
avaiable in the mvebu SoCs (Armada 370/XP, Kirkwood, Dove, ...).

This binding provides an accurate model of the SoC address space,
and allows to declare the address and size of the decoding windows the MBus
needs to access the peripherals, together with the target ID and attribute
for those windows.

The binding is composed of two required nodes: one for the MBus bus
and one for the MBus controller.

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.

85bf6d4e4b drivers: bus: add a new driver for WEIM
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.

f40739faba ARM: dts: OMAP2+: Simplify NAND support
Commit 8c8a777 (ARM: OMAP2+: Add function to read GPMC settings from
device-tree) added a device-tree property "gpmc,device-nand" to indicate
is the GPMC child device is NAND. This commit should have updated the
GPMC NAND documentation (Documentation/devicetree/bindings/mtd/gpmc-nand.txt)
to list the property "gpmc,device-nand" as a required property and also
updated the example. However, this property is redundant and not needed
because the GPMC child device node for NAND is called "nand". Therefore,
remove this property.

d36b4cd46d ARM: OMAP2+: Add additional GPMC timing parameters
Some of the GPMC timings parameters are currently missing from the GPMC
device-tree binding. Add these parameters to the binding documentation
as well as code to read them. Also add either "-ps" or "-ns" suffix to
the GPMC timing properties to indicate whether the timing is in
picoseconds or nanoseconds.

The existing code in gpmc_read_timings_dt() is checking the value of
of_property_read_u32() and only is successful storing the value read
in the gpmc_timings structure. Checking the return value in this case
is not necessary and we can simply read the value, if present, and
store directly in the gpmc_timings structure. Therefore, simplify the
code by removing these checks.

The comment in the gpmc_read_timings_dt() function, "only for OMAP3430"
is also incorrect as it is applicable to all OMAP3+ devices. So correct
this too.

bc6b1e7b86 ARM: OMAP: gpmc: add DT bindings for GPMC timings and NAND
This patch adds basic DT bindings for OMAP GPMC.

The actual peripherals are instantiated from child nodes within the GPMC
node, and the only type of device that is currently supported is NAND.

Code was added to parse the generic GPMC timing parameters and some
documentation with examples on how to use them.

Successfully tested on an AM33xx board.

Adds a new driver *omap-ocp2scp*. This driver takes the responsibility of
creating all the devices that is connected to OCP2SCP. In the case of OMAP4,
USB2PHY is connected to ocp2scp.

This also includes device tree support for ocp2scp driver and
the documentation with device tree binding information is updated.
