+ABB regulator for OMAP platforms
+
+Required properties :
+- compatible:
+ - "ti,omap36xx-abb" for OMAP36XX
+ - "ti,omap4-abb" for OMAP4
+ - "ti,omap5-abb" for OMAP5
+
+- regulator-min-microvolt: lowest OPP voltage
+- regulator-max-microvolt: highest OPP voltage
+- regulator-always-on: ABB should be always on
+- reg: addres range defined in TRM
+- ti,tranxdone_status_mask: ABB transition state mask
+- operating-points: An array of 2-tuples items, and each item consists
+ of voltage and ABB opp_sel, like <volt-uV opp_sel>.
+ volt: voltage in uV
+ opp_sel: 0-bypass, 1-FBB, 2-RBB
+
+Examples :
+abb_mpu_iva: regulator-abb1 {
+ compatible = "ti,omap36xx-abb";
+ regulator-name = "abb_mpu_iva";
+ regulator-min-microvolt = <1012500>;
+ regulator-max-microvolt = <1375000>;
+ regulator-always-on;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ reg = <0x483072f0 0x8>,
+ <0x48306818 0x4>;
+ ti,tranxdone_status_mask = <0x4000000>;
+ operating-points = <
