+      Please refer to pinctrl-bindings.txt in this directory for details of the
+      common pinctrl bindings used by client devices, including the meaning of the
+      phrase "pin configuration node".
+
+      The pin configuration nodes act as a container for an arbitrary number of
+      subnodes. Each of these subnodes represents some desired configuration for a
+      pin, a group, or a list of pins or groups. This configuration can include the
+      mux function to select on those pin(s)/group(s), and various pin configuration
+      parameters, such as pull-up, drive strength, etc.
