Texas Instruments TI-SCI Clocks |
|
=============================== |
|
|
|
All clocks on Texas Instruments' SoCs that contain a System Controller, |
|
are only controlled by this entity. Communication between a host processor |
|
running an OS and the System Controller happens through a protocol known |
|
as TI-SCI[1]. This clock implementation plugs into the common clock |
|
framework and makes use of the TI-SCI protocol on clock API requests. |
|

|

|
|
|
Required properties: |
|
------------------- |
|
- compatible: Must be "ti,k2g-sci-clk" |
|
- #clock-cells: Shall be 2. |
|
In clock consumers, this cell represents the device ID and clock ID |
|
exposed by the PM firmware. The list of valid values for the device IDs |
|
and clocks IDs for 66AK2G SoC are documented at |
|
http://processors.wiki.ti.com/index.php/TISCI#66AK2G02_Data |
|
|
|
Examples: |
|
-------- |
|
|
|
pmmc: pmmc { |
|
compatible = "ti,k2g-sci"; |
|
|
|
k2g_clks: clocks { |
|
compatible = "ti,k2g-sci-clk"; |
|
#clock-cells = <2>; |
|
}; |
|
}; |
|
|
|
uart0: serial@2530c00 { |
|
compatible = "ns16550a"; |
|
clocks = <&k2g_clks 0x2c 0>; |
|
};
