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.yaml 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 */ 31 &spi0 { 32 mux: mux-controller@0 { 33 compatible = "adi,adgs1408"; 34 reg = <0>; 35 spi-max-frequency = <1000000>; 36 #mux-control-cells = <0>; 37 }; 38 } 39 40 adc-mux { 41 compatible = "io-channel-mux"; 42 io-channels = <&adc 1>; 43 io-channel-names = "parent"; 44 mux-controls = <&mux>; 45 46 channels = "out_a0", "out_a1", "test0", "test1", 47 "out_b0", "out_b1", "testb0", "testb1"; 48 };
