Subject: [PATCH v6 1/6] net: stmmac: sun8i: add support for Allwinner H6 EMAC
Date: Mon, 27 May 2019 18:22:32 +0200 [thread overview]
Message-ID: <20190527162237.18495-2-megous@megous.com> (raw)
In-Reply-To: <20190527162237.18495-1-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.
