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>;
|
|
};
