Hi all,
This series adds support for the two Gigabit Ethernet (GBETH) interfaces on the
Renesas RZ/G3E (R9A09G047) SoCs and their enablement on the SMARC-II EVK. This
is achieved by integrating the necessary clock/reset signals prior to defining
common DTS nodes, and enabling both GBETH ports at the board level.
Here are pach dependencies:
- Patch 1/4 is based on renesas-drivers tree, on top of renesas-clk-for-v6.17
branch
- Patches [2,3,4]/4 are based on renesas-devel tree, on top of
renesas-dts-for-v6.17 branch
Below are some test logs, involving pings, then unbind/bind, then pings again:
```
