-PBIAS internal regulator for SD card dual voltage i/o pads on OMAP SoCs.
-
-Required properties:
-- compatible:
-  - should be "ti,pbias-dra7" for DRA7
-  - should be "ti,pbias-omap2" for OMAP2
-  - should be "ti,pbias-omap3" for OMAP3
-  - should be "ti,pbias-omap4" for OMAP4
-  - should be "ti,pbias-omap5" for OMAP5
-  - "ti,pbias-omap" is deprecated
-- reg: pbias register offset from syscon base and size of pbias register.
-- syscon : phandle of the system control module
-- regulator-name : should be
-			pbias_mmc_omap2430 for OMAP2430, OMAP3 SoCs
-			pbias_sim_omap3 for OMAP3 SoCs
-			pbias_mmc_omap4 for OMAP4 SoCs
-			pbias_mmc_omap5 for OMAP5 and DRA7 SoC
-
-Optional properties:
-- Any optional property defined in bindings/regulator/regulator.txt
-
-Example:
-
-		pbias_regulator: pbias_regulator {
-			compatible = "ti,pbias-omap";
-			reg = <0 0x4>;
-			syscon = <&omap5_padconf_global>;
-			pbias_mmc_reg: pbias_mmc_omap5 {
-				regulator-name = "pbias_mmc_omap5";
-				regulator-min-microvolt = <1800000>;
-				regulator-max-microvolt = <3000000>;
-			};
