SP810 System Controller
-----------------------
Required properties:
- compatible: standard compatible string for a Primecell peripheral,
see Documentation/devicetree/bindings/arm/primecell.txt
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"
Example:
sysctl@020000 {
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";
};
