Subject: arm64: dts: imx8mp-evk: Improve the Ethernet PHY description
From: Fabio Estevam <festevam@xxxxxxxxx>
commit 798a1807ab13a38e21c6fecd8d22a513d6786e2d upstream.
According to the datasheet RTL8211, it must be asserted low for at least
10ms and at least 72ms "for internal circuits settling time" before
accessing the PHY registers.
Add properties to describe such requirements.
