Subject: [PATCH 33/35] net: stmmac: sun8i: add support for Allwinner H6 EMAC
|
|
|
|
The EMAC on Allwinner H6 is just like the one on A64. The "internal PHY"
|
|
on H6 is on a co-packaged AC200 chip, and it's not really internal (it's
|
|
connected via RMII at PA GPIO bank).
|
|
|
|
Add support for the Allwinner H6 EMAC in the dwmac-sun8i driver.
