If the common clock framework is enabled, call of_clk_init(NULL) in time_init() to register device tree clocks with the clock framework. After this time_init() calls a new function init_metag_clocks(), which looks for a clock named "core" in the node compatible with "img,meta" (usually the root node). If found the get_core_freq machine callback is overridden to obtain the core clock frequency using that clock.

* Meta Processor Binding
|
|
|
|
This binding specifies what properties must be available in the device tree
|
|
representation of a Meta Processor Core, which is the root node in the tree.
|
|
|
|
Required properties:
|
|
|
|
- compatible: Specifies the compatibility list for the Meta processor.
|
|
The type shall be <string> and the value shall include "img,meta".
|
|
|
|
Optional properties:
|
|
|
|
- clocks: Clock consumer specifiers as described in
|
|
Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
- clock-names: Clock consumer names as described in
|
|
Documentation/devicetree/bindings/clock/clock-bindings.txt.
|
|
|
|
Clocks are identified by name. Valid clocks are:
|
|
|
|
- "core": The Meta core clock from which the Meta timers are derived.
|
|
|
|
* Examples
|
|
|
|
/ {
|
|
compatible = "toumaz,tz1090", "img,meta";
|
|
|
|
clocks = <&meta_core_clk>;
|
|
clock-names = "core";
|
|
};
