Subject: [PATCH 0/2] sun8i: r40: second ethernet support
Date: Sun, 7 Mar 2021 06:13:50 +0300 [thread overview]
Message-ID: <20210307031353.12643-1-boger@wirenboard.com> (raw)
This patch series adds support for two Ethernet ports on Allwinner R40.
R40 (aka V40,A40i,T3) has two different Ethernet IPs called EMAC and GMAC.
EMAC only support 10/100 Mbit in MII mode, while GMAC support both 10/100
(MII) and 10/100/1000 (RGMII).
In contrast to A10/A20 where GMAC and EMAC share the same pins making EMAC
somewhat pointless, on R40 EMAC can be routed to port H.
Both EMAC (on port H) and GMAC (on port A) can be then enabled at the same
time, allowing for two ethernet ports.
