Subject: [PATCH v2 0/4] arm64: dts: st: add ethernet1 controller support on
 stm32mp23/25 boards

All of the current stm32mp2x boards embed an ethernet1 SNPS GMAC5.x
controller.

Add the support for it on stm32mp235f-dk, stm32mp257f-dk and
stm32mp257f-ev1 boards and default enable it.

On the stm32mp257f-ev1 board, we choose to keep the ethernet1
controller as a standalone ethernet controller instead of using
the TSN capable switch.

Changes in v2:
- Remove pointless max-speed properties
- Fix property ordering (reg after compatible) in the stm32mp257f-ev1
- Link to v1: https://lore.kernel.org/r/20250903-mp2_ethernet-v1-0-4105b0ad2344@foss.st.com
