+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
+
+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.
+
+Optional properties:
+
+  - present-gpios : Host present line, indicating the presence of a
+    host system, see [1]. This can be omitted if the present line is
+    tied in hardware.

+

+	compatible = "cirrus,lochnagar2";

+
+	reset-gpios = <&gpio0 55 0>;

+- rohm,reset-snvs-powered : Transfer BD718x7 to SNVS state at reset.
+
+The BD718x7 supports two different HW states as reset target states. States
+are called as SNVS and READY. At READY state all the PMIC power outputs go
+down and OTP is reload. At the SNVS state all other logic and external
+devices apart from the SNVS power domain are shut off. Please refer to NXP
+i.MX8 documentation for further information regarding SNVS state. When a
+reset is done via SNVS state the PMIC OTP data is not reload. This causes
+power outputs that have been under SW control to stay down when reset has
+switched power state to SNVS. If reset is done via READY state the power
+outputs will be returned to HW control by OTP loading. Thus the reset
+target state is set to READY by default. If SNVS state is used the boot
+crucial regulators must have the regulator-always-on and regulator-boot-on
+properties set in regulator node.
