This v3 is a subset of the v1, split-out to simplify the review.
The old patches concerned in v1 where 05/14, 06/14 and 07/14.
This subset:
- introduces the generic pinctrl properties "skew-delay-input" and
"skew-delay-output", as suggested by Linus Walleij;
- applies some cleanup to STM32 pinctrl driver to simplify the following
commits in the series;
- adds support for the I/O synchronization in STM32 pinctrl driver and
bindings;
- updates the DT for STM32MP25 pinctrl to use the new properties.
Changes v2 -> v3:
- rebased on v6.18-rc1;
- replace "skew-delay-direction" with "skew-delay-input" and
"skew-delay-output";
- use generic properties from pincfg-node.yaml in dt-bindings;
- add the new properties to the new node eth1 in DT.
Changes v1 -> v2 subset:
- rebased on v6.17-rc1;
- replace ST property "st,io-delay" with generic "skew-delay";
- replace ST property "st,io-delay-path" with generic "skew-delay-direction";
- collapse the other ST property in a single "st,io-sync";
- Link to v1: https://lore.kernel.org/lkml/20241022155658.1647350-1-ant...
