Subject: [PATCH net-next 0/2] net: phy: disable EEE on TI PHYs
Date: Tue, 11 Nov 2025 11:38:22 +0000 [thread overview]
Message-ID: <aRMgLmIU1XqLZq4i@shell.armlinux.org.uk> (raw)
Hi,
Towards the end of October, we discussed EEE on TI PHYs which seems to
cause problems with the stmmac hardware. This problem was never fully
diagnosed, but it was identified that TI PHYs do not support LPI
signalling, but report that EEE is supported, and they implement the
advertisement registers and that functionality.
This series allows PHY drivers to disable EEE support.
