1 Texas Instruments TI-SCI Clocks
2 ===============================
4 All clocks on Texas Instruments' SoCs that contain a System Controller,
5 are only controlled by this entity. Communication between a host processor
6 running an OS and the System Controller happens through a protocol known
7 as TI-SCI[1]. This clock implementation plugs into the common clock
8 framework and makes use of the TI-SCI protocol on clock API requests.

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 assignments can be found in the header
18 files <dt-bindings/genpd/<soc>.h> (which covers the device IDs) and
19 <dt-bindings/clock/<soc>.h> (which covers the clock IDs), where <soc>
20 is the SoC involved, for example 'k2g'.
