[PATCH v3 0/8] net: stmmac: qcom-ethqos: add support for SCMI power domains

[Bartosz Golaszewski <brgl@bgdev.pl>]

Add support for the firmware-managed variant of the DesignWare MAC on
the sa8255p platform. This series contains new DT bindings 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.

The DTS changes will go in separately.
