Suman Anna 91fa953ea6 dt-bindings: clock: ti-sci: Fix incorrect usage of headers
The clock consumer usage description was erroneously referring to
couple of dt-binding headers that are no longer valid. The definition
and/or usage of these headers is incorrect and the only file present
at the moment, dt-bindings/soc/k2g.h is also being cleaned up. The
examples in this binding were updated properly, but the update to
description was missed out. So, fix this.

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>;
};
