  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".

  Zynq's 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, slew rate, etc.

  Each configuration node can consist of multiple nodes describing the pinmux and
  pinconf options. Those nodes can be pinmux nodes or pinconf nodes.

  The name of each subnode is not important; all subnodes should be enumerated
  and processed purely based on their content.
