+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.
