Subject[PATCH v1 0/3] Support regulators coupling on NVIDIA Tegra20/30

The voltage regulators need to be coupled on NVIDIA Tegra20 and Tegra30
SoCs in order to provide voltage scaling functionality in a generic way.
All necessary regulator-core patches that added support for the regulators
coupling are already have been merge into mainline kernel. This series
adds customized voltage couplers for Tegra20/30 SoCs, paving the way for
a refined CPUFreq driver that will utilize voltage scaling and other neat
features. This is a resend of a leftover patches from a previous series
[1] that was partially applied by Mark Brown. Please review, thanks in
