title: Common multiplexer controller consumer bindings
maintainers:
- Peter Rosin <peda@axentia.se>
description: |
Mux controller consumers should specify a list of mux controllers that they
want to use with a property containing a 'mux-ctrl-list':
mux-ctrl-list ::= <single-mux-ctrl> [mux-ctrl-list]
single-mux-ctrl ::= <mux-ctrl-phandle> [mux-ctrl-specifier]
mux-ctrl-phandle : phandle to mux controller node
mux-ctrl-specifier : array of #mux-control-cells specifying the
given mux controller (controller specific)
Mux controller properties should be named "mux-controls". The exact meaning of
each mux controller property must be documented in the device tree binding for
each consumer. An optional property "mux-control-names" may contain a list of
strings to label each of the mux controllers listed in the "mux-controls"
property.
If it is required to provide the state that the mux controller needs to
be set to, the property "mux-states" must be used. An optional property
"mux-state-names" can be used to provide a list of strings, to label
each of the multiplixer states listed in the "mux-states" property.
Properties "mux-controls" and "mux-states" can be used depending on how
the consumers want to control the mux controller. If the consumer needs
needs to set multiple states in a mux controller, then property
"mux-controls" can be used. If the consumer needs to set the mux
controller to a given state then property "mux-states" can be used.
mux-ctrl-specifier typically encodes the chip-relative mux controller number.
If the mux controller chip only provides a single mux controller, the
mux-ctrl-specifier can typically be left out.

controller to an index into the list given by the "mux-controls" property.

Devices that use more than a single multiplexer state can use the
