Subject: [PATCH v2 06/12] net: ethernet: stmmac: stm32: update config management for phy wo cristal
From: Christophe Roullier <christophe.roullier@...com>
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
Signed-off-by: Christophe Roullier <christophe.roullier@...s.st.com>
