Linux kernel source tree

On Versal TSU clock cannot be disabled irrespective of whether PTP is used. Hence introduce a new Versal config structure with a "need tsu" caps flag and check the same in runtime_suspend/resume before cutting off clocks. More information on this for future reference: This is an IP limitation on versions 1p11 and 1p12 when Qbv is enabled (See designcfg1, bit 3). However it is better to rely on an SoC specific check rather than the IP version because tsu clk property itself may not represent actual HW tsu clock on some chip designs.

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.
