[PATCH 05/11] net: ethernet: stmmac: stm32: update config management for phy wo cristal

From: Christophe Roullier
Date: Thu Apr 11 2024 - 10:42:28 EST


Some cleaning because some Ethernet PHY configs do not need to add
st,ext-phyclk property.
Change print info message "No phy clock provided" only when debug.
