[PATCH AUTOSEL 5.5 03/35] ARM: dts: Fix dm814x Ethernet by changing to use rgmii-id mode

From: Tony Lindgren tony@atomide.com

[ Upstream commit b46b2b7ba6e104d265ab705914859ec0db7a98c5 ]

Commit cd28d1d6e52e ("net: phy: at803x: Disable phy delay for RGMII mode") caused a regression for dm814x boards where NFSroot would no longer work.

Let's fix the issue by configuring "rgmii-id" mode as internal delays are needed that is no longer the case with "rgmii" mode.
