+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.txt
|
|
|
+
|
|
|
+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)
|
|
|
+ */
