Allwinner SoCs do not contain a separate reset controller, instead the reset lines for the various devices are integrated into the "BGR" (Bus Gate / Reset) registers, for each device group: one for all UARTs, one for all SPI interfaces, and so on. The Allwinner CCU driver also doubles as a reset provider, and since the reset lines are indeed just single bits in those BGR register, we can represent them easily in an array of structs, just containing the register offset and the bit number. Add the location of the reset bits for all devices in the A523/T527 SoCs, using the existing sunxi CCU infrastructure.

README
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 reStructuredText 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.
