| SP810 System Controller |
| ----------------------- |
| |
| Required properties: |
| |
| - compatible: standard compatible string for a Primecell peripheral, |
| see Documentation/devicetree/bindings/arm/primecell.yaml |
| for more details |
| should be: "arm,sp810", "arm,primecell" |
| |
| - reg: standard registers property, physical address and size |
| of the control registers |
| |
| - clock-names: from the common clock bindings, for more details see |
| Documentation/devicetree/bindings/clock/clock-bindings.txt; |
| should be: "refclk", "timclk", "apb_pclk" |
| |
| - clocks: from the common clock bindings, phandle and clock |
| specifier pairs for the entries of clock-names property |
| |
| - #clock-cells: from the common clock bindings; |
| should be: <1> |
| |
| - clock-output-names: from the common clock bindings; |
| should be: "timerclken0", "timerclken1", "timerclken2", "timerclken3" |
| |
| - assigned-clocks: from the common clock binding; |
| should be: clock specifier for each output clock of this |
| provider node |
| |
| - assigned-clock-parents: from the common clock binding; |
| should be: phandle of input clock listed in clocks |
| property with the highest frequency |
| |
| Example: |
| v2m_sysctl: sysctl@20000 { |
| compatible = "arm,sp810", "arm,primecell"; |
| reg = <0x020000 0x1000>; |
| clocks = <&v2m_refclk32khz>, <&v2m_refclk1mhz>, <&smbclk>; |
| clock-names = "refclk", "timclk", "apb_pclk"; |
| #clock-cells = <1>; |
| clock-output-names = "timerclken0", "timerclken1", "timerclken2", "timerclken3"; |
| assigned-clocks = <&v2m_sysctl 0>, <&v2m_sysctl 1>, <&v2m_sysctl 3>, <&v2m_sysctl 3>; |
| assigned-clock-parents = <&v2m_refclk1mhz>, <&v2m_refclk1mhz>, <&v2m_refclk1mhz>, <&v2m_refclk1mhz>; |
