Subject: [RFC PATCH 6/6] devicetree: bindings: voltagedomain: add bindings for OMAP compatible SoCs

Add documentation for device tree description for basic voltage domain
for Texas Instruments OMAP compatible SoC family of processors which
controls both bias and supply voltage planes.

+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>;
+};
