This patch adds device tree parsing for gpio_ir_recv platform_data and
the mandatory binding documentation. It basically follows what we already
have for e.g. gpio_keys. All required device tree properties are OS
independent but an optional property allows linux specific support for rc
maps.

The PAMU caches use the LIODNs to determine which cache lines hold the
entries for the corresponding LIODs. The LIODNs must therefore be
carefully assigned to avoid cache thrashing -- two active LIODs with
LIODNs that put them in the same cache line.
Currently, LIODNs are statically assigned by U-Boot, but this has
limitations. LIODNs are assigned even for devices that may be disabled
or unused by the kernel. Static assignments also do not allow for device
drivers which may know which LIODs can be used simultaneously. In
other words, we really should assign LIODNs dynamically in Linux.
To do that, we need to describe the PAMU device and cache topologies in
the device trees.

The CPSW switch can act as Dual EMAC by segregating the switch ports
using VLAN and port VLAN as per the TRM description in
14.3.2.10.2 Dual Mac Mode
Following CPSW components will be common for both the interfaces.
* Interrupt source is common for both eth interfaces
* Interrupt pacing is common for both interfaces
* Hardware statistics is common for all the ports
* CPDMA is common for both eth interface
* CPTS is common for both the interface and it should not be enabled on
both the interface as timestamping information doesn't contain port
information.
Constrains
* Reserved VID of One port should not be used in other interface which will
enable switching functionality
* Same VID must not be used in both the interface which will enable switching
functionality

From Dinh Nguyen, this is a series of patches introducing support for
socfpga hardware (Altera Cyclone5). It also includes a cleanup that
moves some of the ARMv7 cache maintenance functions to a common location,
since three other platforms aready implemented it separately.
* socfpga/hw:
arm: socfpga: Add SMP support for actual socfpga harware
arm: Add v7_invalidate_l1 to cache-v7.S
arm: socfpga: Add entries to enable make dtbs socfpga
arm: socfpga: Add new device tree source for actual socfpga HW

This patch adds a simple Device Tree binding for the mvsdio driver, as
well as the necessary documentation for it. Compatibility with non-DT
platforms is preserved, by keeping the platform_data based
initialization.
We introduce a small difference between non-DT and DT platforms: DT
platforms are required to provide a clocks = <...> property, which the
driver uses to get the frequency of the clock that goes to the SDIO
IP. The behaviour on non-DT platforms is kept unchanged: a clock
reference is not mandatory, but the clock frequency must be passed in
the "clock" field of the mvsdio_platform_data structure.

This mxs usbphy is only needs to be on after system boots
up, and software never needs to control it anymore.
Meanwhile, usbphy's parent needs to be notified if usb
is suspend or not. So we design below mxs usbphy usage:
- usbphy1_gate and usbphy2_gate:
Their parents are dummy clock, we only needs to enable
it after system boots up.
- usbphy1 and usbphy2
Usage reserved bit for this clock, in that case, the refcount
will be updated, but without hardware changing.

Some matrix keypad drivers can support different numbers of rows and
columns. Add a generic binding for these.
Implementation note:
In order to implement this binding in the kernel, we will need to modify
matrix_keypad_() to look up the number of rows and cols in
the keymap. Perhaps this could be done by passing 0 for these parameters?
Many of the parameters can already be set to NULL. Ick.
