[PATCH v2 2/5] arm64: dts: meson: fix PHY deassert timing requirements

2020-12-01 Thread Stefan Agner
According to the datasheet (Rev. 1.9) the RTL8211F requires at least 72ms "for internal circuits settling time" before accessing the PHY egisters. This fixes an issue seen on ODROID-C2 where the Ethernet link doesn't come up when using ip link set down/up: [ 6630.714855] meson8b-dwmac
