[PATCH v3 3/3] arm64: dts: qcom: ipq5018: Enable mdio1 and add QCA8081 PHY on rdp432-c2

From: Luo Jie

Date: Wed Sep 02 2026 - 06:31:06 EST


The RDP432-c2 board uses an external QCA8081 PHY on mdio1 for one
of its Ethernet connections, but mdio1 is left disabled at the
board level. Enable mdio1 with a 6.25MHz MDIO clock and describe
the QCA8081 PHY at address 0x1c.
