Stephen Warren d0e381ca8c clk: tegra: Mark fuse clock as critical
commit bf83b96f87 upstream.

For a little over a year, U-Boot on Tegra124 has configured the flow
controller to perform automatic RAM re-repair on off->on power
transitions of the CPU rail[1]. This is mandatory for correct operation
of Tegra124. However, RAM re-repair relies on certain clocks, which the
kernel must enable and leave running. The fuse clock is one of those
clocks. Mark this clock as critical so that LP1 power mode (system
suspend) operates correctly.

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.
