[PATCH v2 0/5] Enable ethernet for qcs8300

[YijieYang]

From: Yijie Yang <quic_yijiyang@quicinc.com>

Add dts nodes to enable ethernet interface on qcs8300-ride and
Rev 2 platforms.
The EMAC, SerDes and EPHY version are the same as those in sa8775p.

[PATCH v2 4/5] arm64: dts: qcom: move common parts for qcs8300-ride variants into a .dtsi

[YijieYang]

From: Yijie Yang <quic_yijiyang@quicinc.com>

In order to support multiple revisions of the qcs8300-ride board, create
a .dtsi containing the common parts and split out the ethernet bits into
the actual board file as they will change in revision 2.

[PATCH v2 5/5] arm64: dts: qcom: qcs8300-ride-r2: add new board file

[YijieYang]

From: Yijie Yang <quic_yijiyang@quicinc.com>

Revision 2 of the qcs8300-ride board uses a different PHY for the two
ethernet ports and supports 2.5G speed. Create a new file for the board
reflecting the changes.

If you don't intend to modify these specific configs, you can drop
the labels from child pin nodes

The rest looks good

Generally refactors happen first and features are added later, but
I know how painful it is to reorder changes in a patchset, so I'm
not going to ask you to do that.

This looks unintended

The rest looks good, except I think you forgot to drop /dts-v1/
from the dtsi
