1Bindings for Analog Devices ADGS1408/1409 8:1/Dual 4:1 Mux
2
3Required properties:
4- compatible : Should be one of
5	* "adi,adgs1408"
6	* "adi,adgs1409"
7* Standard mux-controller bindings as described in mux-controller.txt
8
9Optional 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
17Optional 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
22States 0 through 7 correspond to signals S1 through S8 in the datasheet.
23For ADGS1409 only states 0 to 3 are available.
24
25Example:
26
27	/*
28	 * One mux controller.
29	 * Mux state set to idle as is (no idle-state declared)
30	 */
