Subject: [PATCH net-next 6/7] dt-bindings: deprecate "snps,en-tx-lpi-clockgating" property
Date: Sun, 09 Mar 2025 15:02:14 +0000	[thread overview]
Message-ID: <E1trIAQ-005nto-3w@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.

Therefore, snps,en-tx-lpi-clockgating is technically incorrect, so this
commit deprecates the property in the binding.
