-Texas Instruments OMAP compatible OPP supply description
-
-OMAP5, DRA7, and AM57 family of SoCs have Class0 AVS eFuse registers which
-contain data that can be used to adjust voltages programmed for some of their
-supplies for more efficient operation. This binding provides the information
-needed to read these values and use them to program the main regulator during
-an OPP transitions.
-
-Also, some supplies may have an associated vbb-supply which is an Adaptive Body
-Bias regulator which much be transitioned in a specific sequence with regards
-to the vdd-supply and clk when making an OPP transition. By supplying two
-regulators to the device that will undergo OPP transitions we can make use
-of the multi regulator binding that is part of the OPP core described here [1]
-to describe both regulators needed by the platform.

-
-Required Properties for Device Node:
-- vdd-supply: phandle to regulator controlling VDD supply
-- vbb-supply: phandle to regulator controlling Body Bias supply
-             (Usually Adaptive Body Bias regulator)
-
-Required Properties for opp-supply node:
-- compatible: Should be one of:
-       "ti,omap-opp-supply" - basic OPP supply controlling VDD and VBB
-       "ti,omap5-opp-supply" - OMAP5+ optimized voltages in efuse(class0)VDD
-                           along with VBB
-       "ti,omap5-core-opp-supply" - OMAP5+ optimized voltages in efuse(class0) VDD
-                           but no VBB.
-- reg: Address and length of the efuse register set for the device (mandatory
-       only for "ti,omap5-opp-supply")
-- ti,efuse-settings: An array of u32 tuple items providing information about
-       optimized efuse configuration. Each item consists of the following:
-       volt: voltage in uV - reference voltage (OPP voltage)
-       efuse_offseet: efuse offset from reg where the optimized voltage is stored.
-- ti,absolute-max-voltage-uv: absolute maximum voltage for the OPP supply.
-
-Example:
-
-/* Device Node (CPU)  */
-cpus {
-       cpu0: cpu@0 {
-               device_type = "cpu";
-
-               ...
-
-               vdd-supply = <&vcc>;
-               vbb-supply = <&abb_mpu>;
-       };
-};
-
-/* OMAP OPP Supply with Class0 registers */
-opp_supply_mpu: opp_supply@4a003b20 {
-       compatible = "ti,omap5-opp-supply";
-       reg = <0x4a003b20 0x8>;
-       ti,efuse-settings = <
-       /* uV   offset */
-       1060000 0x0
-       1160000 0x4
-       1210000 0x8
-       >;
-       ti,absolute-max-voltage-uv = <1500000>;
