Binding for Samsung S2M and S5M family clock generator block
|
|
============================================================
|
|
|
|
This is a part of device tree bindings for S2M and S5M family multi-function
|
|
devices.
|
|
More information can be found in bindings/mfd/sec-core.txt file.
|
|
|
|
The S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz
|
|
outputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs.
|
|
|
|
To register these as clocks with common clock framework instantiate under
|
|
main device node a sub-node named "clocks".
|
|
|
|
It uses the common clock binding documented in:
|
|
- Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
|
|
Required properties of the "clocks" sub-node:
|
|
- #clock-cells: should be 1.
|
|
- compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk",
|
|
"samsung,s2mps14-clk", "samsung,s5m8767-clk"
|
|
The S2MPS15 uses the same compatible as S2MPS13, as both provides similar
|
|
clocks.
|
|
|
|
|
|
Each clock is assigned an identifier and client nodes use this identifier
|
|
to specify the clock which they consume.

Include dt-bindings/clock/samsung,s2mps11.h file to use preprocessor defines
|
|
in device tree sources.
|
|
|
|
|
|
Example:
|
|
|
|
s2mps11_pmic@66 {
|
|
compatible = "samsung,s2mps11-pmic";
|
|
reg = <0x66>;
|
|
|
|
s2m_osc: clocks {
|
|
compatible = "samsung,s2mps11-clk";
|
|
#clock-cells = <1>;
|
|
clock-output-names = "xx", "yy", "zz";
|
|
};
|
|
};
