Zero clock rate doesn't make sense for PLLs and tegra-clk driver enters into infinite loop on trying to calculate PLL parameters for zero rate. Make code to error out if requested rate is zero. Originally this trouble was found by Robert Yang while he was trying to bring up upstream kernel on Samsung Galaxy Tab, which happened due to a bug in Tegra DRM driver that erroneously sets PLL rate to zero. This issues came over again recently during of kernel bring up on ASUS TF700T. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com> |

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.
