	Hi Vinod et al,

While there exist several optional_get() PHY helper functions, there is
no optional variant of devm_of_phy_get(), leading to several drivers
implementing this theirselves, sometimes in buggy ways.

Hence this series, after two cleanup patches, introduces a
devm_of_phy_optional_get() helper(), and converts existing users of
devm_of_phy_get() where appropriate.

Changes compared to v1[1]:
  - Incorporate "[PATCH v2 1/9] phy: Remove unused phy_optional_get()",
    as it touches the same documentation,
  - New patch "[PATCH v2 2/9] doc: phy: Document devm_of_phy_get()",
  - Print an error message in case of failure, as requested by RobH,
  - Update Documentation,
  - Clarify removed checks for -ENODEV and -ENOSYS,
  - Remove error printing in case of real failures from callers,
  - Rebase am65-cpsw change on top of commit 854617f52ab42418 ("net:
    ethernet: ti: am65-cpsw: Handle -EPROBE_DEFER for Serdes PHY") in
    net-next (next-20230123 and later),
  - Add Reviewed-by, Acked-by.

Most of this series been compile-tested only, but the new helper itself
has been tested with a new user[2].

Thanks for your comments!
