Add a common clock driver for basic gpio controlled clock multiplexers. This driver can be used for devices like 5V41068A or 831721I from IDT or for discrete multiplexer circuits. The 'select' pin selects one of two parent clocks.

Binding for simple gpio clock multiplexer.
|
|
|
|
This binding uses the common clock binding[1].
|
|
|
|
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
Required properties:
|
|
- compatible : shall be "gpio-mux-clock".
|
|
- clocks: list of two references to parent clocks.
|
|
- #clock-cells : from common clock binding; shall be set to 0.
|
|
- select-gpios : GPIO reference for selecting the parent clock.
|
|
|
|
Example:
|
|
clock {
|
|
compatible = "gpio-mux-clock";
|
|
clocks = <&parentclk1>, <&parentclk2>;
|
|
#clock-cells = <0>;
|
|
select-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
|
|
};
