-Cirrus Logic Lochnagar Audio Development Board
-
-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.txt
-
-Required properties:
-
-  - compatible : One of the following strings:
-                 "cirrus,lochnagar-pinctrl"
-
-  - gpio-controller : Indicates this device is a GPIO controller.
-  - #gpio-cells : Must be 2. The first cell is the pin number, see
-    [3] for available pins and the second cell is used to specify
-    optional parameters, see [1].
-  - gpio-ranges : Range of pins managed by the GPIO controller, see
-    [1]. Both the GPIO and Pinctrl base should be set to zero and the
-    count to the appropriate of the LOCHNAGARx_PIN_NUM_GPIOS define,
-    see [3].
-
-  - pinctrl-names : A pinctrl state named "default" must be defined.
-  - pinctrl-0 : A phandle to the default pinctrl state.
-
-Required sub-nodes:
-
-The pin configurations are defined as a child of the pinctrl states
-node, see [2]. Each sub-node can have the following properties:
