[ Upstream commit 3fcce133f0d9a50d3a23f8e2bc950197b4e03900 ] regmap is a library function that gets selected by drivers that need it. No driver modules should depend on it. Instead depends on SPI and select REGMAP_SPI. Depending on REGMAP_SPI makes this driver only build if another driver already selected REGMAP_SPI, as the symbol can't be selected through the menu kernel configuration.

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.
