| 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"; |
| }; |
