On peripherals communicating over a relatively slow SPI line (e.g. tcan4x5x), individual transfers have high fixed costs. This causes the driver to spend most of its time waiting between transfers and severely limits throughput. Reduce these overheads by reading more than one word at a time. Writing could get a similar treatment in follow-on commits.

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.
