Subject: ipq806x: ecw5410: drop GPIO based MDIO1 node
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fa3646c0033eb93d6397b55c1a4e921dff1049f8;p=openwrt%2Fstaging%2Fjow.git

ipq806x: ecw5410: drop GPIO based MDIO1 node

It looks like this is a leftover before there was a proper MDIO driver.
Since both PHY-s are connected to the HW MDIO bus there is no reason for
this to exist anymore, especially since it uses the same pins as the HW
controller and has the pinmux for the set to "MDIO" so this worked by
pure luck as GPIO MDIO would probe first and override the HW driver.

Move the GMAC3 to simply use the same MDIO bus phandle.
