Binding for Imagination Technologies MIPS Boston clock sources.
This binding uses the common clock binding[1].

The device node must be a child node of the syscon node corresponding to the
Boston system's platform registers.
Required properties:
- compatible : Should be "img,boston-clock".
- #clock-cells : Should be set to 1.
Values available for clock consumers can be found in the header file:
<dt-bindings/clock/boston-clock.h>
Example:
system-controller@17ffd000 {
compatible = "img,boston-platform-regs", "syscon";
reg = <0x17ffd000 0x1000>;
clk_boston: clock {
compatible = "img,boston-clock";
#clock-cells = <1>;

Representing flash partitions in devicetree
Flash partitions in device tree
===============================
Partitions can be represented by sub-nodes of an mtd device. This can be used
Flash devices can be partitioned into one or more functional ranges (e.g. "boot
code", "nvram", "kernel").
Different devices may be partitioned in a different ways. Some may use a fixed
flash layout set at production time. Some may use on-flash table that describes
the geometry and naming/purpose of each functional region. It is also possible
to see these methods mixed.
To assist system software in locating partitions, we allow describing which
method is used for a given flash device. To describe the method there should be
a subnode of the flash device that is named 'partitions'. It must have a
'compatible' property, which is used to identify the method to use.
We currently only document a binding for fixed layouts.
Fixed Partitions
================
Partitions can be represented by sub-nodes of a flash device. This can be used
on platforms which have strong conventions about which portions of a flash are
used for what purposes, but which don't use an on-flash partition table such
as RedBoot.
The partition table should be a subnode of the mtd node and should be named
The partition table should be a subnode of the flash node and should be named
'partitions'. This node should have the following property:
- compatible : (required) must be "fixed-partitions"
Partitions are then defined in subnodes of the partitions node.
For backwards compatibility partitions as direct subnodes of the mtd device are
For backwards compatibility partitions as direct subnodes of the flash device are
supported. This use is discouraged.
NOTE: also for backwards compatibility, direct subnodes that have a compatible
string are not considered partitions, as they may be used for other bindings.
#address-cells & #size-cells must both be present in the partitions subnode of the
mtd device. There are two valid values for both:
flash device. There are two valid values for both:
<1>: for partitions that require a single 32-bit cell to represent their
size/address (aka the value is below 4 GiB)
<2>: for partitions that require two 32-bit cells to represent their
size/address (aka the value is 4 GiB or greater).
Required properties:
- reg : The partition's offset and size within the mtd bank.
- reg : The partition's offset and size within the flash
Optional properties:
- label : The label / name for this partition. If omitted, the label is taken
