From 7e0b9a29934d228bec9a133f504f283903333029 Mon Sep 17 00:00:00 2001
From: "Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>

Subject: [PATCH 5/6] net: dsa: hellcreek: convert to
phylink_generic_validate()
Populate the supported interfaces and MAC capabilities for the
hellcreek DSA switch and remove the old validate implementation to
allow DSA to use phylink_generic_validate() for this switch driver.
The switch actually only supports MII and RGMII, but as phylib defaults
to GMII, we need to include this interface mode to keep existing DT
working.
