Subject: [PATCH] arm64: dts: allwinner: a523: Add GMAC200 ethernet controller
|
|
|
|
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.
