      1NVIDIA Tegra Regulators Coupling
      2================================
      3
      4NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
      5Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
      6there are 2.
      7
      8Tegra20 voltage coupling
      9------------------------
     10
     11On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
     12The CORE and RTC voltages shall be in a range of 170mV from each other
     13and they both shall be higher than the CPU voltage by at least 120mV.
     14
     15Tegra30 voltage coupling
     16------------------------
     17
     18On Tegra30 SoC's there are 2 coupled regulators: CORE and CPU. The CORE
     19and CPU voltages shall be in a range of 300mV from each other and CORE
     20voltage shall be higher than the CPU by N mV, where N depends on the CPU
     21voltage.
     22
     23Required properties:
     24- nvidia,tegra-core-regulator: Boolean property that designates regulator
     25  as the "Core domain" voltage regulator.
     26- nvidia,tegra-rtc-regulator: Boolean property that designates regulator
     27  as the "RTC domain" voltage regulator.
     28- nvidia,tegra-cpu-regulator: Boolean property that designates regulator
     29  as the "CPU domain" voltage regulator.

     38				regulator-max-microvolt = <1300000>;
     39				regulator-coupled-with = <&rtc_vdd_reg &cpu_vdd_reg>;
     40				regulator-coupled-max-spread = <170000 550000>;
     41
     42				nvidia,tegra-core-regulator;

     51
     52				nvidia,tegra-rtc-regulator;
     53			};
     54
     55			cpu_vdd_reg: cpu {
