Subject: [PATCH v3 1/2] ARM: dts: imx6q-tbs2910: Add an mdio node
Date: Mon, 13 Jul 2020 10:05:08 -0300 [thread overview]
Message-ID: <20200713130509.20105-1-festevam@gmail.com> (raw)
imx6q-tbs2910 has an Atheros AR8035 Ethernet PHY at address 4.
The AR8035 provides a 125MHz clock to the ENET_REF_CLK i.MX6 pin.
Improve the Ethernet representation by adding an mdio node with such
information.
This fixes an Ethernet regression in U-Boot as U-Boot AR803X driver now
expects the 'qca,clk-out-frequency' property to be passed via
device tree.
