This is actually a clock controller block that hw designers decided was
good place to shove the ipc bits (because there's room!). Can we call it

l2cc: clock-controller@2011000 {
compatible = "syscon";
reg = <0x2011000 0x1000>;
};

yep, I will rename this in next version.

Eventually I'll add the specific krait compatible when we merge krait
clock support:
sounds good.

--srini

l2cc: clock-controller@2011000 {
compatible = "qcom,kpss-gcc", "syscon";
reg = <0x2011000 0x1000>;
clock-output-names = "acpu_l2_aux";
};

+ reg = <0x108000 0x1000>;
+ qcom,ipc = <&apcs 0x8 2>;

There are actually 3 ipc bits. I guess if we ever have to use the other
two we'll extend this binding to have the other bits specified some
other way?
