[ Upstream commit c8c4353685778e75e186103411e9d01a4a3f2b90 ]
The temperature output register of the Loongson-2K2000 is defined in the
chip configuration domain, which is different from the Loongson-2K1000,
so it can't be fallbacked.
We need to use two groups of registers to describe it: the first group
is the high and low temperature threshold setting register; the second
group is the temperature output register.
It is true that this fix will cause ABI corruption, but it is necessary
otherwise the Loongson-2K2000 temperature sensor will not work properly.

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.
