Subject: [PATCH V2 07/12] net-next: mediatek: add support for rt3883
Date: Fri, 26 Feb 2016 15:21:39 +0100 [thread overview]
Message-ID: <1456496504-50429-8-git-send-email-blogic@openwrt.org> (raw)
In-Reply-To: <1456496504-50429-1-git-send-email-blogic@openwrt.org>
Add support for rt3883 and its smaller version rt3662. They both have a
single gBit port that will normally be attached to an external phy or
switch. There are not many rt3883 based routers in the field. I think
there is a second MAC on these SoCs. Due to lack of hardware utilizing this
I never added support. RT3883 is somewhat unique as it is the only SoC made
by Ralink that uses the mips74 core.
