The Zynq platform has PCAP, ICAP and JTAG interfaces for configuring programmable logic (PL). The existing driver implementation uses the PCAP interface to configure the PL. Before switching the PL configuration interface from PCAP to ICAP make sure that all outstanding Transactions relevant to the PL configuration should be completed by the PCAP interface otherwise it may lead to PL configuration issues. This patch provides a required fix to ensure that all existing PL transactions are completed before switching from PCAP to ICAP. For detailed information relevant to PL configuration interfaces refer Zynq 7000 TRM (section 6.5.1).

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.
