[PATCH net-next v2 0/3] riscv: sophgo: Add ethernet support for SG2042

[Inochi Amaoto]

The ethernet controller of SG2042 is Synopsys DesignWare IP with
tx clock. Add device id for it.

This patch can only be tested on a SG2042 evb board, as pioneer
does not expose this device.

The user dts patch link:
https://lore.kernel.org/linux-riscv/cover.1751700954.git.rabenda.cn@gmail.com

Change form v1:
1. add user link at cover
2. separate the devicetree patch as a standalone series
3. patch 1: Apply Conor's tag
