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 v4:
- Fixed email threading
- Link to v3: https://lore.kernel.org/r/20250528-renesas-serdes-update-v3-0-8413fcd70dba@renesas.com
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
