X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=aa5014dd1a58aa8902f2aaf4a02b76998ac2eb2b;p=openwrt%2Fstaging%2F981213.git

ramips: mt7620n: enable port 4 as EPHY by default

According to the datasheet the mt7620n have a fixed switch configuration
with 5 ephy (10/100) port. No RGMII configuration is possible.

Drop the mdio node as well. Without RGMII, the mdio node doesn't make any
sense
