-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.
-
-Also see these documents for generic binding information:
- [1] GPIO : ../gpio/gpio.txt
-
-And these for relevant defines:
- [2] include/dt-bindings/pinctrl/lochnagar.h
- [3] include/dt-bindings/clock/lochnagar.h
-
-And these documents for the required sub-node binding details:
- [4] Clock: ../clock/cirrus,lochnagar.txt
- [5] Pinctrl: ../pinctrl/cirrus,lochnagar.txt
- [6] Regulator: ../regulator/cirrus,lochnagar.txt
- [7] Sound: ../sound/cirrus,lochnagar.txt
- [8] Hardware Monitor: ../hwmon/cirrus,lochnagar.txt
-
-Required properties:
-
- - compatible : One of the following strings:
- "cirrus,lochnagar1"
- "cirrus,lochnagar2"
-
- - reg : I2C slave address
-
- - reset-gpios : Reset line to the Lochnagar, see [1].
-
-Required sub-nodes:
-
- - lochnagar-clk : Binding for the clocking components, see [4].
-
- - lochnagar-pinctrl : Binding for the pin control components, see [5].
-
-Optional sub-nodes:
-
- - Bindings for the regulator components, see [6]. Only available on
- Lochnagar 2.
-
- - lochnagar-sc : Binding for the sound card components, see [7].
- Only available on Lochnagar 2.
- - lochnagar-hwmon : Binding for the hardware monitor components, see [8].
- Only available on Lochnagar 2.
-
-Optional properties:
-
- - present-gpios : Host present line, indicating the presence of a
