The exact meaning of 23 each mux controller property must be documented in the device tree binding for 24 each consumer. An optional property "mux-control-names" may contain a list of 25 strings to label each of the mux controllers listed in the "mux-controls" 26 property. 27 28 If it is required to provide the state that the mux controller needs to 29 be set to, the property "mux-states" must be used. An optional property 30 "mux-state-names" can be used to provide a list of strings, to label 31 each of the multiplixer states listed in the "mux-states" property. 32 33 Properties "mux-controls" and "mux-states" can be used depending on how 34 the consumers want to control the mux controller. If the consumer needs 35 needs to set multiple states in a mux controller, then property 36 "mux-controls" can be used. If the consumer needs to set the mux 37 controller to a given state then property "mux-states" can be used. 38 39 mux-ctrl-specifier typically encodes the chip-relative mux controller number. 40 If the mux controller chip only provides a single mux controller, the 41 mux-ctrl-specifier can typically be left out. 42 43select: true 44 45properties: 46 mux-controls: 47 $ref: /schemas/types.yaml#/definitions/phandle-array 48 49 mux-states: 50 $ref: /schemas/types.yaml#/definitions/phandle-array 51 52 mux-control-names: 53 description: 54 Devices that use more than a single mux controller can use the 55 "mux-control-names" property to map the name of the requested mux 56 controller to an index into the list given by the "mux-controls" property. 57 58 mux-state-names: 59 description: 60 Devices that use more than a single multiplexer state can use the 61 "mux-state-names" property to map the name of the requested mux 62 controller to an index into the list given by the "mux-states" 63 property. 64 65additionalProperties: true 66 67... 68
