Lina Iyer 52cd845181 devicetree: bindings: Document qcom,idle-states
Document cpuidle states of QCOM cpus. In addition to arm-idle-state
compatible string, the ARM idle state definition must define one of the
following compatible strings -
	"qcom,idle-state-ret",
	"qcom,idle-state-spc",
	"qcom,idle-state-pc",

The compatibles helps the SPM platform driver to use the correct idle
function when the index to the idle state is passed to the platform
driver.

David Brown 97f00f7120 SSBI: Convert SSBI to device tree
The SSBI bus is exclusive to the Qualcomm MSM targets, and all SoCs
using it will be using device tree.  Convert this driver to indentify
with device tree.

This makes the bus probing a good bit simpler, since the attaching of
child nodes can be represented directly in the devicetree, rather than
having to be inferred by name.

Stephen Boyd eebdb0c1e1 ARM: msm: Rework timer binding to be more general
The msm timer binding I wrote is bad. First off, the clock
frequency in the binding for the dgt is wrong. Software divides
down the input rate by 4 to achieve the rate listed in the
binding. We also treat each individual timer as a separate
hardware component, when in reality there is one timer block
(that may be duplicated per cpu) with multiple timers within it.
Depending on the version of the hardware there can be one or two
general purpose timers, status and divider control registers, and
an entirely different register layout.

In the next patch we'll need to know about the different register
layouts so that we can properly check the status register after
clearing the count. The current binding makes this complicated
because the general purpose timer's reg property doesn't indicate
where that status register is, and in fact it is beyond the size
of the reg property.

Clean all this up by just having one node for the timer hardware,
and describe all the interrupts and clock frequencies supported
while having one reg property that covers the entire timer
register region. We'll use the compatible field in the future to
determine different register layouts and if we should read the
status registers, etc.
