This list used to be sort on description.
Since rk3566/rk3568 it's out of order. Heiko?

properties:
$nodename:
pattern: "^(|usb-|usb2-|usb3-|pci-|pcie-|sata-)phy(@[0-9a-f,]+)*$"
The phy nodename is used by a phy-handle.
The parent node is compatible with "snps,dwmac-mdio",
so change nodename to 'ethernet-phy', for which '#phy-cells'
is not a required property

Also for rock-5a board.
