Subject: [PATCH 0/9] net: stmmac: qcom-ethqos: add support for SCMI power
 domains

Add support for the firmware-managed variant of the DesignWare MAC on
the sa8255p platform. This series contains new DT bindings, new DTS
nodes and driver changes required to support the MAC in the STMMAC
driver.

It also reorganizes the ethqos code quite a bit to make the introduction
of power domains into the driver a bit easier on the eye.
