[PATCH 7/8] arm64: dts: imx8mm-kontron: Fix reset delays for ethernet PHY
From: Frieder Schrempf
Date: Thu Sep 30 2021 - 11:57:27 EST
From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>
According to the datasheet the VSC8531 PHY expects a reset pulse of 100 ns
and a delay of 15 ms after the reset has been deasserted. Set the matching
values in the devicetree.
