SPI flash require 8 dummy clock cycle during read operation before it can receive the data. However, this might not needed by other SPI device such as SD card when operate in SPI mode. Thus, a new device tree property called 'dummy-cycle' is added to resolve this issue. This optional device tree property is needed for controlling the SPI flash device.

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.
