+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.
+
+- clocks:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: reference to the xo clock.
+
+- clock-names:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "xo".
+
+- 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>;
+ clocks = <&xo_board>;
+ clock-names = "xo";
+ 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>;
+ clocks = <&xo_board>;
+ clock-names = "xo";
+ clock-output-names = "hfpll0";
+ };
