Hi,

This patch set adds the following to the r8a779f0-ether-serdes driver:

 * USXGMII mode support for 2.5GBit/s ethernet Phys
 * A new configuration step suggested by the latest R-Car S4-8 users
   manual V. 1.20.

Changes in v3:
- Fixed wrong macro (reported by kernel test bot).
- Link to v2: https://lore.kernel.org/r/20250527-renesas-serdes-update-v2-0-ef17c71cd94c@renesas.com

Changes from v1:
 - Modify this driver for the R-Car S4-8 only
 - So, this patch set drops the followings:
 -- any dt doc modification
 -- X5H support.
 -- 5GBASER support
 -- Registers' macros

Thanks,

Michael
