net: stmmac: correct MAC propagation delay
Changes in v3:
- work in Richard's review feedback. Thank you for reviewing my patch:
- as some of the hardware may have no or invalid correction value
registers: introduce feature switch which can be enabled in the glue
code drivers depending on the actual hardware support
- only enable the feature on the i.MX8MP for the time being, as the patch
improves timing accuracy and is tested for this hardware
- Link to v2: https://lore.kernel.org/r/20230719-stmmac_correct_mac_delay-v2-1-3366f38ee9a6@pengutronix.de
Changes in v2:
- fix builds for 32bit, this was found by the kernel build bot
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202307200225.B8rmKQPN-lkp@intel.com/
- while at it also fix an overflow by shifting a u32 constant from macro by 10bits
by casting the constant to u64

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.
