Add regulators coupler for Tegra20 SoCs that performs voltage balancing of a coupled regulators and thus provides voltage scaling functionality. There are 3 coupled regulators on all Tegra20 SoCs: CORE, RTC and CPU. The CORE and RTC voltages shall be in range of 170mV from each other and they both shall be higher than the CPU voltage by at least 120mV. This sounds like it could be handle by a generic voltage balancer, but the CORE voltage scaling isn't implemented in any of the upstream drivers yet. It will take quite some time and effort to hook up voltage scaling for all of the drivers, hence we will use a custom coupler that will manage the CPU voltage scaling for the starter.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
