+Cirrus Logic Arizona class audio SoCs
+
+These devices are audio SoCs with extensive digital capabilities and a range
+of analogue I/O.
+
+This document lists regulator specific bindings, see the primary binding
+document:
+  ../mfd/arizona.txt
+
+Required properties:
+
+  - AVDD-supply, DBVDD1-supply, CPVDD-supply : Power supplies for the device,
+    as covered in regulator.txt
+
+  - DBVDD2-supply, DBVDD3-supply : Additional databus power supplies (wm5102,
+    wm5110, wm8280, wm8998, wm1814)
+
+  - SPKVDDL-supply, SPKVDDR-supply : Speaker driver power supplies (wm5102,
+    wm5110, wm8280, wm8998, wm1814)
+
+  - SPKVDD-supply : Speaker driver power supply (wm8997)
+
+Optional properties:
+  - wlf,ldoena : GPIO specifier for the GPIO controlling LDOENA
+
+  - DCVDD-supply, MICVDD-supply : Power supplies, only need to be specified if
+    they are being externally supplied. As covered in
+    Documentation/devicetree/bindings/regulator/regulator.txt
+
+Optional subnodes:
+  - ldo1 : Initial data for the LDO1 regulator, as covered in
+    Documentation/devicetree/bindings/regulator/regulator.txt
+  - micvdd : Initial data for the MICVDD regulator, as covered in
+    Documentation/devicetree/bindings/regulator/regulator.txt
