[PATCH v4 v0/4] sa8155p-adp devicetree ethernet cleanup

[PATCH v4 v0/4] sa8155p-adp devicetree ethernet cleanup

[Andrew Halaney]

This series cleans up some devicetree conventions in sa8155p-adp based
on feedback from other platforms.

The hope is that by getting it right here, future contributors won't
repeat the same mistakes as I did!

[PATCH v4 1/4] arm64: dts: qcom: sa8155p-adp: Make compatible the first property

[Andrew Halaney]

As stated at the below link in another review, compatible is always the
first property.

Follow suit here to avoid copying incorrectly in the future.

[PATCH v4 2/4] arm64: dts: qcom: Make -cells decimal

[Andrew Halaney]

The property logically makes sense in decimal, and is the standard used
elsewhere.

[PATCH v4 3/4] arm64: dts: qcom: sa8155p-adp: Remove unneeded rgmii_phy information

[Andrew Halaney]

Using interrupts-extended already indicates what the interrupt-parent
is, so drop the explicit interrupt-parent.

The comment about this being the phy-intr is not helpful either, since
this is the only interrupt in the phy node.

[PATCH v4 4/4] arm64: dts: qcom: sa8155p-adp: Move mtl nodes into ethernet node

[Andrew Halaney]

The mtl nodes aren't evaluated unless they're under the node with the
compatible. Move them so they're now evaluated in case future patchsets
modify them incorrectly.

An example of this can be seen in the link.

Hey Bjorn,

I think this one is ready to be picked up. Just a gentle reminder, I
