The Spreadtrum platform uses a special set/clear method to update registers' bits, thus this patch set registers a physical regmap bus into syscon core to support this feature instead of using the MMIO bus, which is not a physical regmap bus. Any comments are welcome. Thanks. Changes from RFC v1: - Add new helper to registers a physical regmap bus instead of using the MMIO bus.

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 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.
