description: |
  Lochnagar is an evaluation and development board for Cirrus Logic
  Smart CODEC and Amp devices. It allows the connection of most Cirrus
  Logic devices on mini-cards, as well as allowing connection of various
  application processor systems to provide a full evaluation platform.
  Audio system topology, clocking and power can all be controlled through
  the Lochnagar, allowing the device under test to be used in a variety of
  possible use cases.

  This binding document describes the binding for the pinctrl portion of
  the driver.

  Also see these documents for generic binding information:
    [1] GPIO : ../gpio/gpio.txt
    [2] Pinctrl: ../pinctrl/pinctrl-bindings.txt

  And these for relevant defines:
    [3] include/dt-bindings/pinctrl/lochnagar.h

  This binding must be part of the Lochnagar MFD binding:
    [4] ../mfd/cirrus,lochnagar.yaml
