1Texas Instruments TI-SCI Clocks 2=============================== 3 4All clocks on Texas Instruments' SoCs that contain a System Controller, 5are only controlled by this entity. Communication between a host processor 6running an OS and the System Controller happens through a protocol known 7as TI-SCI[1]. This clock implementation plugs into the common clock 8framework and makes use of the TI-SCI protocol on clock API requests. 9 10[1] Documentation/devicetree/bindings/arm/keystone/ti,sci.txt 11 12Required properties: 13------------------- 14- compatible: Must be "ti,k2g-sci-clk" 15- #clock-cells: Shall be 2. 16 In clock consumers, this cell represents the device ID and clock ID 17 exposed by the PM firmware. The list of valid values for the device IDs 18 and clocks IDs for 66AK2G SoC are documented at 19 http://processors.wiki.ti.com/index.php/TISCI#66AK2G02_Data 20 21Examples: 22-------- 23 24pmmc: pmmc { 25 compatible = "ti,k2g-sci"; 26 27 k2g_clks: clocks { 28 compatible = "ti,k2g-sci-clk"; 29 #clock-cells = <2>; 30 }; 31}; 32 33uart0: serial@2530c00 { 34 compatible = "ns16550a"; 35 clocks = <&k2g_clks 0x2c 0>; 36}; 37
