cfdab2cd85In commit 0e3b8a81f5df ("spi: spi-geni-qcom: Add interconnect
support") the spi_geni_runtime_suspend() and spi_geni_runtime_resume()
became a bit slower. Measuring on my hardware I see numbers in the
hundreds of microseconds now.
Let's use autosuspend to help avoid some of the overhead. Now if
we're doing a bunch of transfers we won't need to be constantly
chruning.
The number 250 ms for the autosuspend delay was picked a bit
arbitrarily, so if someone has measurements showing a better value we
could easily change this.

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.
