Subject: [PATCH] arm64: dts: meson: odroidc2: readd PHY reset properties
|
|
|
|
The sync of the device tree and dt-bindings from Linux v5.6-rc2
|
|
11a48a5a18c6 ("Linux 5.6-rc2") causes Ethernet to break on some
|
|
ODROID-C2. The PHY seems to need proper reset timing to be functional
|
|
in U-Boot and Linux afterwards. Readd the old PHY reset bindings for
|
|
dwmac until we support the new bindings in the PHY node.
|
|
|
|
Fixes: dd5f2351e99a ("arm64: dts: meson: sync dt and bindings from v5.6-rc2")
