+Texas Instruments OMAP compatible voltage domain description
+
+This binding uses [1] and describes the voltage domain devices
+typically used on Texas Instruments OMAP compatible SoC family of
+processors.
+
+[1] Documentation/devicetree/bindings/power/voltdm/voltage_domain.txt
+
+Required Properties:
+- compatible: Should be one of:
+ "ti,omap-voltdm" - basic voltage domain controlling VDD and VBB
+- vdd-supply: phandle to regulator controlling VDD supply
+- vbb-supply: phandle to regulator controlling Body Bias supply
+ (Usually Adaptive Body Bias regulator)
+- #voltdm-cells: shall be <0>
+
+Example:
+voltage_domain_mpu: voltdm@1 {
+ compatible = "ti,omap-voltdm";
+ #voltdm-cells = <0>;
+
+ vdd-supply = <&vcc>;
+ vbb-supply = <&abb_mpu>;
+};
