The USB Host Controller driver 'ohci-at91.c' reads a Special Function Register - OHCI Interrupt Configuration Register (AT91_SFR_OHCIICR) for bits SUSPEND_A/B/C. These bits are defined in sama5d2 alone, so sfr register mapping is done with compatible string "atmel,sama5d2-sfr". This gives a kernel warning 'failed to find sfr node' with non sama5d2 cpus which is removed here, thus leaving it up to having a proper DTS.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
