-This module is part of the MAX77650 MFD device. For more details

-
-The regulator controller is represented as a sub-node of the PMIC node

-
-The device has a single LDO regulator and a SIMO buck-boost regulator with

-Required properties:
---------------------
-- compatible:		Must be "maxim,max77650-regulator"
-
-Each rail must be instantiated under the regulators subnode of the top PMIC
-node. Up to four regulators can be defined. For standard regulator properties
-refer to Documentation/devicetree/bindings/regulator/regulator.txt.
-
-Available regulator compatible strings are: "ldo", "sbb0", "sbb1", "sbb2".

+NVIDIA Tegra Regulators Coupling
+================================
+
+NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
+Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
+there are 2.
+
+Tegra20 voltage coupling
+------------------------
+
+On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
+The CORE and RTC voltages shall be in a range of 170mV from each other
+and they both shall be higher than the CPU voltage by at least 120mV.
+
+Tegra30 voltage coupling
+------------------------
+
+On Tegra30 SoC's there are 2 coupled regulators: CORE and CPU. The CORE
+and CPU voltages shall be in a range of 300mV from each other and CORE
+voltage shall be higher than the CPU by N mV, where N depends on the CPU
+voltage.
+
+Required properties:
+- nvidia,tegra-core-regulator: Boolean property that designates regulator
+  as the "Core domain" voltage regulator.
+- nvidia,tegra-rtc-regulator: Boolean property that designates regulator
+  as the "RTC domain" voltage regulator.
+- nvidia,tegra-cpu-regulator: Boolean property that designates regulator
+  as the "CPU domain" voltage regulator.
+
+Example:
+
+	pmic {
+		regulators {
+			core_vdd_reg: core {
+				regulator-name = "vdd_core";
+				regulator-min-microvolt = <950000>;
+				regulator-max-microvolt = <1300000>;
+				regulator-coupled-with = <&rtc_vdd_reg &cpu_vdd_reg>;
+				regulator-coupled-max-spread = <170000 550000>;
+
+				nvidia,tegra-core-regulator;
+			};
+
+			rtc_vdd_reg: rtc {
+				regulator-name = "vdd_rtc";
+				regulator-min-microvolt = <950000>;
+				regulator-max-microvolt = <1300000>;
+				regulator-coupled-with = <&core_vdd_reg &cpu_vdd_reg>;
+				regulator-coupled-max-spread = <170000 550000>;
+
+				nvidia,tegra-rtc-regulator;
+			};
+
+			cpu_vdd_reg: cpu {
+				regulator-name = "vdd_cpu";
+				regulator-min-microvolt = <750000>;
+				regulator-max-microvolt = <1125000>;
+				regulator-coupled-with = <&core_vdd_reg &rtc_vdd_reg>;
+				regulator-coupled-max-spread = <550000 550000>;
+
+				nvidia,tegra-cpu-regulator;
+			};
+		};
+	};
