On NVIDIA Tegra30 there is a requirement for regulator "A" to have voltage higher than voltage of regulator "B" by N microvolts, the N value changes depending on the voltage of regulator "B". This is similar to min-spread between voltages of regulators, the difference is that the spread value isn't fixed. This means that extra carefulness is required for regulator "A" to drop its voltage without violating the requirement, hence its voltage should be changed in steps so that its couple "B" could follow (there is also max-spread requirement). Add new "max_uV_step" constraint that breaks voltage change into several steps, each step is limited by the max_uV_step value.

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.
