    +High-Frequency PLL (HFPLL)
    +
    +PROPERTIES
    +
    +- compatible:
    + Usage: required
    + Value type: <string>:
    + shall contain only one of the following. The generic
    + compatible "qcom,hfpll" should be also included.
    +
    + "qcom,hfpll-ipq8064", "qcom,hfpll"
    + "qcom,hfpll-apq8064", "qcom,hfpll"
    + "qcom,hfpll-msm8974", "qcom,hfpll"
    + "qcom,hfpll-msm8960", "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-ipq8064", "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-ipq8064", "qcom,hfpll";
    + reg = <0xf908a000 0x30>, <0xf900a000 0x30>;
    + clock-output-names = "hfpll0";
    + };
