Subject: [PATCH v2 2/2] ARM: dts: imx6q-tbs2910: Add an mdio node
Date: Thu, 25 Jun 2020 08:18:46 -0300 [thread overview]
Message-ID: <20200625111846.9507-2-festevam@gmail.com> (raw)
In-Reply-To: <20200625111846.9507-1-festevam@gmail.com>
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.
