This driver was added by commit0fc6a323e1("spi: bcm53xx: driver for SPI controller on Broadcom bcma SoC") back in 2014. It was needed to provide a minimal support for SPI controller on BCM5301X (AKA Northstar) devices. An alternative driver was added by Kamal in commitfa236a7ef2("spi: bcm-qspi: Add Broadcom MSPI driver") 2 years later. It supports the same hardware but for some reason a new driver has been developed for it. At this point the new driver supports: more modes, setting a speed, setting bits per word and uses IRQs instead of polling. DTS file for BCM5301X has also been updated in the commit1c8f406507("ARM: dts: BCM5301X: convert to iProc QSPI") - over a year ago. That explained I see no reason to keep the old driver alive.

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.
