- 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
