The linux-next integration testing tree

The Zynq QSPI controller features 2 CS. When the num-cs DT property is set to 2, the hardware will be initialized to support having two devices connected over each CS. In this case, both CS lines are driven by the state of the U_PAGE (upper page) bit. When unset, the lower page (CS0) is selected, otherwise it is the upper page (CS1). Change tested on a custom design featuring two SPI-NORs with different CS on the Zynq-7000 QSPI bus.

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.
