From: Daniel Golle Date: Mon, 28 Aug 2023 22:44:52 +0000 (+0100) Subject: arm-trusted-firmware-mediatek: enable built-in 2.5G PHY on MT7988 X-Git-Url: http://git.openwrt.org/openwrt/feeds.git?a=commitdiff_plain;h=33046d2a471ed687404a617c356b9cdf5652c2d6;p=openwrt%2Fstaging%2Fwigyori.git 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.
