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.

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
