Subject: [PATCH 1/2] dt-bindings: net: ipq4019-mdio: add IPQ9574 compatible

Add a compatible property specific to IPQ9574. This should be used
along with the IPQ4019 compatible. This second compatible serves the
same purpose as the ipq{5,6,8} compatibles. This is to indicate that
the clocks properties are required.

Subject: [PATCH 2/2] arm64: dts: qcom: ipq9574: add MDIO bus

The IPQ95xx uses an IPQ4019 compatible MDIO controller that is already
supported. Add a DT node to expose it.

Please pad the size part to 8 hex digits with leading zeroes
