-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>;
