Subject: [PATCH AUTOSEL 5.4 010/108] net: phy: mscc: accept all RGMII species in vsc85xx_mac_if_set

From: Vladimir Oltean <vladimir.oltean@....com>

[ Upstream commit da206d65f2b293274f8082a26da4e43a1610da54 ]

The helper for configuring the pinout of the MII side of the PHY should
do so irrespective of whether RGMII delays are used or not. So accept
the ID, TXID and RXID variants as well, not just the no-delay RGMII
variant.
