Subject: [PATCH net-next 5/7] ARM: dts: stm32: remove "snps,en-tx-lpi-clockgating" property
Date: Sun, 09 Mar 2025 15:02:08 +0000	[thread overview]
Message-ID: <E1trIAK-005nti-W5@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <Z82tWYZulV12Pjir@shell.armlinux.org.uk>

Whether the MII transmit clock can be stopped is primarily a property
of the PHY (there is a capability bit that should be checked first.)
Whether the MAC is capable of stopping the transmit clock is a separate
issue, but this is already handled by the core DesignWare MAC code.

As commit "net: stmmac: stm32: use PHY capability for TX clock stop"
adds the flag to use the PHY capability, remove the DT property that is
now unecessary.
