From babc5544c2933a5cbf9389679507dfa4911101ee Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Tue, 16 Oct 2018 13:50:53 +0300 Subject: arm64: dts: clearfog-gt-8k: 1G eth PHY reset signal This reset signal controls the Marvell 1512 1G PHY. Note that current implementation queries the PHY over the MDIO bus (get_phy_device() call from of_mdiobus_register_phy()) before reset signal deassert. If the PHY reset signal is asserted at boot time, PHY registration fails. So current code relies on the bootloader to deassert the reset signal.
