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. [1] Documentation/devicetree/bindings/arm/keystone/ti,sci.txt 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>; };
