It allows the connection of most Cirrus15  Logic devices on mini-cards, as well as allowing connection of various16  application processor systems to provide a full evaluation platform.17  Audio system topology, clocking and power can all be controlled through18  the Lochnagar, allowing the device under test to be used in a variety of19  possible use cases.20 21  This binding document describes the binding for the pinctrl portion of22  the driver.23 24  Also see these documents for generic binding information:25    [1] GPIO : ../gpio/gpio.txt26    [2] Pinctrl: ../pinctrl/pinctrl-bindings.txt27 28  And these for relevant defines:29    [3] include/dt-bindings/pinctrl/lochnagar.h30 31  This binding must be part of the Lochnagar MFD binding:32    [4] ../mfd/cirrus,lochnagar.yaml33 34properties:35  compatible:36    enum:37      - cirrus,lochnagar-pinctrl38 39  gpio-controller: true40 41  '#gpio-cells':42    description:43      The first cell is the pin number and the second cell is used44      to specify optional parameters.45    const: 246 47  gpio-ranges:48    description:49      Range of pins managed by the GPIO controller, see [1].
