Subject: arm64: allwinner: sun50i-a64: add dwmac-sun8i Ethernet driver
|
||
|
|
|
||
|
|
The dwmac-sun8i is an Ethernet MAC that supports 10/100/1000 Mbit
|
||
|
|
connections. It is very similar to the device found in the Allwinner
|
||
|
|
H3, but lacks the internal 100 Mbit PHY and its associated control
|
||
|
|
bits.
|
||
|
|
This adds the necessary bits to the Allwinner A64 SoC .dtsi, but keeps
|
||
|
|
it disabled at this level.
