Subject: arm64: dts: mt7622: fix switch probe on bananapi-r64
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=df768350a87031971a3c834b480aef6ad6f1f1a0;p=linux.git

arm64: dts: mt7622: fix switch probe on bananapi-r64

After commit 868ff5f4944a
("net: dsa: mt7530-mdio: read PHY address of switch from device tree")
the mt7531 switch on Bananapi-R64 was not detected.

mt7530-mdio mdio-bus:00: reset timeout
mt7530-mdio mdio-bus:00: probe with driver mt7530-mdio failed with error -110

Fix this by adding phy address in devicetree.
