Subject: [PATCH v2 03/13] net: stmmac: sun8i: add support for Allwinner H6 EMAC
Date: Tue, 9 Apr 2019 02:24:42 +0200 [thread overview]
Message-ID: <20190409002452.14551-4-megous@megous.com> (raw)
In-Reply-To: <20190409002452.14551-1-megous@megous.com>
From: Icenowy Zheng <icenowy@aosc.io>
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.
