Hi Maxime,

Done in v2, added as patch 1:

  https://lore.kernel.org/all/20260717065933.2629501-1-gahing@gahingwoo.com/

It rewords clock_in_out so that for RGMII, "output" means the SoC drives
a 25 MHz reference out to a crystal-less PHY. The driver change is now
patch 2 of the same series.

Thanks,
Jiaxing
