[PATCH RFT net-next 05/10] arm64: dts: allwinner: a523: Add GMAC200 ethernet controller

Tue Jul 1 09:57:51 PDT 2025
From: Chen-Yu Tsai <wens at csie.org>
The A523 SoC family has a second ethernet controller, called the
GMAC200. It is not exposed on all the SoCs in the family.
Add a device node for it. All the hardware specific settings are from
the vendor BSP.
