This patch adds support for accuracy retrieval on fixed clocks. It also adds a new dt property called 'clock-accuracy' to define the clock accuracy. This can be usefull for oscillator (RC, crystal, ...) definitions which are always given an accuracy characteristic.

Binding for simple fixed-rate clock sources.
|
|
|
|
This binding uses the common clock binding[1].
|
|
|
|
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
Required properties:
|
|
- compatible : shall be "fixed-clock".
|
|
- #clock-cells : from common clock binding; shall be set to 0.
|
|
- clock-frequency : frequency of clock in Hz. Should be a single cell.
|
|
|
|
Optional properties:
|
|
- clock-accuracy : accuracy of clock in ppb (parts per billion).
|
|
Should be a single cell.
|
|
- gpios : From common gpio binding; gpio connection to clock enable pin.
|
|
- clock-output-names : From common clock binding.
|
|
|
|
Example:
|
|
clock {
|
|
compatible = "fixed-clock";
|
|
#clock-cells = <0>;
|
|
clock-frequency = <1000000000>;
|
|
clock-accuracy = <100>;
|
|
};
