Linux kernel source tree

HW can have different input/output delays for each of the pins. Currently, only E82X adapters have delay compensation based on TSPLL config and E810 adapters have constant 1 ms compensation, both cases only for output delays and the same one for all pins. E825 adapters have different delays for SDP and other pins. Those delays are also based on direction and input delays are different than output ones. This is the main reason for moving delays to pin description structure. Add a field in ice_ptp_pin_desc structure to reflect that. Delay values are based on approximate calculations of HW delays based on HW spec. Implement external timestamp (input) delay compensation. Remove existing definitions and wrappers for periodic output propagation delays.

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 reStructuredText 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.
