Bindings for Analog Devices ADGS1408/1409 8:1/Dual 4:1 Mux
Required properties:
- compatible : Should be one of
* "adi,adgs1408"
* "adi,adgs1409"
* Standard mux-controller bindings as described in mux-controller.yaml
Optional properties for ADGS1408/1409:
- gpio-controller : if present, #gpio-cells is required.
- #gpio-cells : should be <2>
- First cell is the GPO line number, i.e. 0 to 3
for ADGS1408 and 0 to 4 for ADGS1409
- Second cell is used to specify active high (0)
or active low (1)
Optional properties:
- idle-state : if present, the state that the mux controller will have
when idle. The special state MUX_IDLE_AS_IS is the default and
MUX_IDLE_DISCONNECT is also supported.
States 0 through 7 correspond to signals S1 through S8 in the datasheet.
For ADGS1409 only states 0 to 3 are available.
Example:
/*
* One mux controller.
* Mux state set to idle as is (no idle-state declared)
*/
&spi0 {
mux: mux-controller@0 {
compatible = "adi,adgs1408";
reg = <0>;
spi-max-frequency = <1000000>;
#mux-control-cells = <0>;
};
}
