This driver does not restore stop > 3 state, so it limits itself to states which do not lose full state or TB. The POWER10 SPRs are sufficiently different from P9 that it seems easier to split out the P10 code. The POWER10 deep sleep code (e.g., the BHRB restore) has been taken out, but it can be re-added when stop > 3 support is added.

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.
