+On some devices (MSM8974 for example), the HFPLLs are
+instantiated within the Krait processor subsystem as separate
+register regions. Add a driver for these PLLs so that we can
+provide HFPLL clocks for use by the system.

++High-Frequency PLL (HFPLL)
++
++PROPERTIES
++
++- compatible:
++	Usage: required
++	Value type: <string>
++	Definition: must be "qcom,hfpll"
++
++- reg:
++	Usage: required
++	Value type: <prop-encoded-array>
++	Definition: address and size of HPLL registers. An optional second
++		    element specifies the address and size of the alias
++		    register region.
++
++- clock-output-names:
++	Usage: required
++	Value type: <string>
++	Definition: Name of the PLL. Typically hfpllX where X is a CPU number
++		    starting at 0. Otherwise hfpll_Y where Y is more specific
++		    such as "l2".
++
++Example:
++
++1) An HFPLL for the L2 cache.
++
++	clock-controller@f9016000 {
++		compatible = "qcom,hfpll";
++		reg = <0xf9016000 0x30>;
++		clock-output-names = "hfpll_l2";
++	};
++
++2) An HFPLL for CPU0. This HFPLL has the alias register region.
++
++	clock-controller@f908a000 {
++		compatible = "qcom,hfpll";
++		reg = <0xf908a000 0x30>, <0xf900a000 0x30>;
++		clock-output-names = "hfpll0";
