-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;
-			};
-		};
-	};
