Hi all,
these patches should be orthogonal to the ongoing work of Peter Geis
that aims to introduce the GMAC1 node to the common RK356x dts.
The GMAC0 node, which is exclusive to the RK3568, and the Ethernet
phy nodes in the RK3568 EVB1 are introduced by this series.
v2:
- sort properties alphabetically
- use phy-mode "rgmii-id" without delay properties
- rename phy nodes to "ethernet-phy"
Best regards,
Michael

While both RK3566 and RK3568 feature the gmac1 node, the gmac0
node is exclusive to the RK3568.
