13   Please refer to pinctrl-bindings.txt in this directory for details of the
15   phrase "pin configuration node".
17   Zynq's pin configuration nodes act as a container for an arbitrary number of
19   pin, a group, or a list of pins or groups. This configuration can include the
20   mux function to select on those pin(s)/group(s), and various pin configuration
21   parameters, such as pull-up, slew rate, etc.
