|
----------------------- |
|
|
|
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>; |
