1 Bindings for Analog Devices ADGS1408/1409 8:1/Dual 4:1 Mux
2
3 Required properties:
4 - compatible : Should be one of
5 * "adi,adgs1408"
6 * "adi,adgs1409"
7 * Standard mux-controller bindings as described in mux-controller.yaml
8
9 Optional properties for ADGS1408/1409:
10 - gpio-controller : if present, #gpio-cells is required.
11 - #gpio-cells : should be <2>
12 - First cell is the GPO line number, i.e. 0 to 3
13 for ADGS1408 and 0 to 4 for ADGS1409
14 - Second cell is used to specify active high (0)
15 or active low (1)
16
17 Optional properties:
18 - idle-state : if present, the state that the mux controller will have
19 when idle. The special state MUX_IDLE_AS_IS is the default and
20 MUX_IDLE_DISCONNECT is also supported.
21
22 States 0 through 7 correspond to signals S1 through S8 in the datasheet.
23 For ADGS1409 only states 0 to 3 are available.
24
25 Example:
26
27 /*
28 * One mux controller.
29 * Mux state set to idle as is (no idle-state declared)
