[PATCH v2 0/2] net: stmmac: dwmac-qcom-ethqos: Add QCS9100 ethqos compatible

[PATCH v2 0/2] net: stmmac: dwmac-qcom-ethqos: Add QCS9100 ethqos compatible

[Tengfei Fan]

Introduce support for the QCS9100 SoC device tree (DTSI) and the
QCS9100 RIDE board DTS. The QCS9100 is a variant of the SA8775p.
While the QCS9100 platform is still in the early design stage, the
QCS9100 RIDE board is identical to the SA8775p RIDE board, except it
mounts the QCS9100 SoC instead of the SA8775p SoC.

The QCS9100 SoC DTSI is directly renamed from the SA8775p SoC DTSI, and
all the compatible strings will be updated from "SA8775p" to "QCS9100".
The QCS9100 device tree patches will be pushed after all the device tree
bindings and device driver patches are reviewed.

The final dtsi will like:

[PATCH v2 1/2] dt-bindings: net: qcom,ethqos: add description for qcs9100

[Tengfei Fan]

Add the compatible for the MAC controller on qcs9100 platforms.
QCS9100 is drived from SA8775p. Currently, both the QCS9100 and SA8775p
platform use non-SCMI resource. In the future, the SA8775p platform will
move to use SCMI resources and it will have new sa8775p-related device
tree. Consequently, introduce "qcom,qcs9100-ethqos" to describe non-SCMI
based ethqos.

After considering the feedback provided on the subject, We have decided

[PATCH v2 2/2] net: stmmac: dwmac-qcom-ethqos: add support for emac4 on qcs9100 platforms

[Tengfei Fan]

QCS9100 uses EMAC version 4, add the relevant defines, rename the
has_emac3 switch to has_emac_ge_3 (has emac greater-or-equal than 3)
and add the new compatible.
QCS9100 is drived from SA8775p. Currently, both the QCS9100 and SA8775p
platform use non-SCMI resource. In the future, the SA8775p platform will
move to use SCMI resources and it will have new sa8775p-related device
tree. Consequently, introduce "qcom,qcs9100-ethqos" to the ethqos device
match table.

These patches are for netdev, so you need to follow the netdev
rules, i.e. the subject should be have [PATCH net-next] in it, etc as
documented over here:

This blurb isn't capturing what's done in this change, please make it

Hi Tengfei

If i remember correctly, there was a similar comment made to one of
the patches in the huge v1 series.

The commit messages are very important, just as important as the code
itself. Please review them all and fixup issues like this before you
repost.

I'm assuming that this is a patch for net-next.
But the commit above is not present in net-next,
and this series doesn't apply to net-next.

Please rebase when preparing v3.
And please designate the target tree in the subject.

	Subject: [PATCH net-next v3] ...

Thanks!
