Yes the PHY goes on the MDIO bus and the pattern is only needed for
backward compatibility.
The pattern was specific to ethernet-phy in the past, but Rob removed it
in commit ac8fe40c3628 ("dt-bindings: net: renesas: Drop ethernet-phy
node schema"). Have something changed and I should revert that as part
of this patch?
I agree it should be listed as deprecated, would this diff work for you?
+# In older bindings there where no mdio child-node to describe the MDIO bus
+# and the PHY. To not fail older bindings accept any node with an address. New
+# users should describe the PHY inside the mdio child-node.
patternProperties:
"@[0-9a-f]$":
type: object
+ deprecated: true
Depending on if Rob's patch should be reverted in whole or in part I
could also try to revert the pattern to "^ethernet-phy@[0-9a-f]$" if you
wish. Please let me know what looks best to you.
