Hello,

This series adds support for standalone PCIe Multilink configuration
along with the support for PCIe Multilink + USB configuration in the
Torrent SERDES driver.

Series is based on linux-next tagged next-20250109.

v2:
https://lore.kernel.org/r/20250106131925.263240-1-s-vadapalli@ti.com/
Changes since v2:
- Rebased series on next-20250109.
- Based on feedback received from:
  Christophe JAILLET <christophe.jaillet@wanadoo.fr>
  a) "const" has been used wherever applicable i.e.:
  s/static struct cdns_reg_pairs/static const struct cdns_reg_pairs
  s/static struct cdns_torrent_vals/static const struct cdns_torrent_vals
  b) Commenting style in patch 2 has been fixed.

v1:
https://lore.kernel.org/r/20240615093433.3659829-1-s-vadapalli@ti.com/
Changes since v1:
- Rebased series on next-20250106.
- Significant changes have been made in the second patch of the series
  in the process of rebasing. Support for 3 or more links was introduced
  and this series had to be modified to be compatible with those changes.
- Added "Co-developed-by" tag in the second patch since some of the
  changes in this series in the process of rebasing were made by me
  which are quite different from the v1 version of the patch.
- Due to these changes, I have *not* collected the "Tested-by" tag on the
  v1 series from Enric Balletbo i Serra <eballetbo@redhat.com>
  and I hope that this series can be tested.

***NOTE***
Since I don't have the hardware required to validate PCIe Multilink +
USB functionality, kindly *do not merge* this series until it gets a
"Tested-by" tag with proper validation of the functionality.

Regards,
Siddharth.
