The "hard" QSPI peripheral on PolarFire SoC is derived from version 2 of the FPGA IP core. The original binding had no fallback etc, so this device tree is valid as is. There was also no functional driver for the QSPI IP, so no device with a devicetree from a previous mainline release will regress.

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.
