Subject: [PATCH v2] ARM: qcom: Add initial APQ8064 SoC and IFC6410 board device trees

Add basic APQ8064 SoC include device tree and support for basic booting on
the IFC6410 board.

Signed-off-by: Kumar Gala <[email protected]>

v2:
* created a v2.0 apq8064.dtsi to handle differences in Si rev in future
* changed /include/ to #include
* added PMU node
* dropped interrupts from cpus node, not currently part of binding

Hi Kumar,

extra space around numbers.

I wonder what is the preferred way of describing the properties:

reg = <0x02000000 0x1000>,
<0x02002000 0x1000>;
or

reg = <0x02000000 0x1000>, <0x02002000 0x1000>;

This file mixes the above two ways of describing.

I suspect the arm-soc folks would like us to split the mach-qcom
changes from the dts changes.

This doesn't follow the binding. We're supposed to put the
compatible in each cpu node even though it's always the same.

This would be "qcom,arch-cache" if the binding is accepted.

These interrupts here are also not accepted as a binding yet.

Nit: Weird two newlines here
