| GPIO-based multiplexer controller bindings |
| Define what GPIO pins are used to control a multiplexer. Or several |
| multiplexers, if the same pins control more than one multiplexer. |
| - compatible : "gpio-mux" |
| - mux-gpios : list of gpios used to control the multiplexer, least |
| - #mux-control-cells : <0> |
| * Standard mux-controller bindings as decribed in mux-controller.txt |
| - idle-state : if present, the state the mux will have when idle. The |
| special state MUX_IDLE_AS_IS is the default. |
| The multiplexer state is defined as the number represented by the |
| multiplexer GPIO pins, where the first pin is the least significant |
| bit. An active pin is a binary 1, an inactive pin is a binary 0. |
| #mux-control-cells = <0>; |
| mux-gpios = <&pioA 0 GPIO_ACTIVE_HIGH>, |
| <&pioA 1 GPIO_ACTIVE_HIGH>; |
| compatible = "io-channel-mux"; |
| io-channel-names = "parent"; |
| channels = "sync-1", "in", "out", "sync-2"; |
