Subject: [PATCH v2 06/12] net: ethernet: stmmac: stm32: update config management for phy wo cristal
Date: Thu, 28 Sep 2023 14:24:21 +0200	[thread overview]
Message-ID: <20230928122427.313271-7-christophe.roullier@foss.st.com> (raw)
In-Reply-To: <20230928122427.313271-1-christophe.roullier@foss.st.com>

From: Christophe Roullier <christophe.roullier@st.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@foss.st.com>
