From a2ffbc8d1604bf0e71962c76ec4e7feec5fda102 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Mon, 28 Aug 2023 23:44:52 +0100 Subject: [PATCH] arm-trusted-firmware-mediatek: enable built-in 2.5G PHY on MT7988 Always enable built-in 2.5G PHY on MT7988 for now, so that it can be used. In future it would be nice to be able to switch power and MDIO access via address 0 at run-time in Linux, both, to be able to use external PHYs at address 0 and to reduce power consumption on systems not using the built-in 2.5G PHY.
