Dnvidia,tegra-regulators-coupling.txt4 NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
5 Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
8 Tegra20 voltage coupling
9 ------------------------
11 On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
12 The CORE and RTC voltages shall be in a range of 170mV from each other
16 ------------------------
24 - nvidia,tegra-core-regulator: Boolean property that designates regulator
26 - nvidia,tegra-rtc-regulator: Boolean property that designates regulator
27 as the "RTC domain" voltage regulator.
