It allows the connection of most Cirrus 15 Logic devices on mini-cards, as well as allowing connection of various 16 application processor systems to provide a full evaluation platform. 17 Audio system topology, clocking and power can all be controlled through 18 the Lochnagar, allowing the device under test to be used in a variety of 19 possible use cases. 20 21 This binding document describes the binding for the pinctrl portion of 22 the driver. 23 24 Also see these documents for generic binding information: 25 [1] GPIO : ../gpio/gpio.txt 26 [2] Pinctrl: ../pinctrl/pinctrl-bindings.txt 27 28 And these for relevant defines: 29 [3] include/dt-bindings/pinctrl/lochnagar.h 30 31 This binding must be part of the Lochnagar MFD binding: 32 [4] ../mfd/cirrus,lochnagar.yaml 33 34 properties: 35 compatible: 36 enum: 37 - cirrus,lochnagar-pinctrl 38 39 gpio-controller: true 40 41 '#gpio-cells': 42 description: 43 The first cell is the pin number and the second cell is used 44 to specify optional parameters. 45 const: 2 46 47 gpio-ranges: 48 description: 49 Range of pins managed by the GPIO controller, see [1].
