This patch adds support for indirect access to the registers via parent regmap. The use case is, the spi master is a sub device of a Multifunction device, which is connected to host by some indirect bus. To support this device type, a new platform_device_id is introduced, and the driver tries to get parent regmap for register accessing like many MFD sub device drivers do.

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.
