-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 regulator portion
-of the driver.
-
-Also see these documents for generic binding information:
-  [1] Regulator: ../regulator/regulator.txt
-
-This binding must be part of the Lochnagar MFD binding:
-  [2] ../mfd/cirrus,lochnagar.txt
-
-Optional sub-nodes:
-
-  - VDDCORE : Initialisation data for the VDDCORE regulator, which
-    supplies the CODECs digital core if it has no build regulator for that
-    purpose.
-      Required Properties:
-      - compatible : One of the following strings:
-                     "cirrus,lochnagar2-vddcore"
-      - SYSVDD-supply: Primary power supply for the Lochnagar.
-
-  - MICVDD : Initialisation data for the MICVDD regulator, which
-    supplies the CODECs MICVDD.
-      Required Properties:
-      - compatible : One of the following strings:
-                     "cirrus,lochnagar2-micvdd"
-      - SYSVDD-supply: Primary power supply for the Lochnagar.
-
-  - MIC1VDD, MIC2VDD : Initialisation data for the MICxVDD supplies.
-      Required Properties:
-      - compatible : One of the following strings:
-                     "cirrus,lochnagar2-mic1vdd", "cirrus,lochnagar2-mic2vdd"
-      Optional Properties:
-      - cirrus,micbias-input : A property selecting which of the CODEC
-        minicard micbias outputs should be used, valid values are 1 - 4.
-      - MICBIAS1-supply, MICBIAS2-supply: Regulator supplies for the
-        MICxVDD outputs, supplying the digital microphones, normally
-        supplied from the attached CODEC.
-
-  - VDD1V8 : Recommended fixed regulator for the VDD1V8 regulator, which supplies the
-    CODECs analog and 1.8V digital supplies.
-      Required Properties:
-      - compatible : Should be set to "regulator-fixed"
-      - regulator-min-microvolt : Should be set to 1.8V
-      - regulator-max-microvolt : Should be set to 1.8V
-      - regulator-boot-on
-      - regulator-always-on
-      - vin-supply : Should be set to same supply as SYSVDD
-
-Example:
-
-lochnagar {
-	lochnagar-micvdd: MICVDD {
-		compatible = "cirrus,lochnagar2-micvdd";
-
-		SYSVDD-supply = <&wallvdd>;
-
-		regulator-min-microvolt = <3300000>;
