Subject: [PATCH] arm64: dts: mt7622: fix switch probe on bananapi-r64
Date: Thu, 16 May 2024 22:48:47 +0200 [thread overview]
Message-ID: <20240516204847.171029-1-linux@fw-web.de> (raw)
From: Frank Wunderlich <frank-w@public-files.de>
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.
Signed-off-by: Frank Wunderlich <frank-w@public-files.de>
