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.
|
||
|
|
|
||
|
|
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.

Devices that use more than a single mux controller can use the
|
||
|
|
"mux-control-names" property to map the name of the requested mux
|
||
|
|
controller to an index into the list given by the "mux-controls" property.
