Subject: [PATCH v4 0/8] 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 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.
Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

Changes in v4:
- Remove the phys property from the SCMI bindings
- Mark the power-domain-names property as required
- Set maxItems for power-domains to 1 for all existing bindings to
maintain the current requirements after modifying the value in the
top-level document
- Link to v3: https://lore.kernel.org/r/20251027-qcom-sa8255p-emac-v3-0-75767b9230ab@linaro.org
Changes in v3:
- Drop 'power' and 'perf' prefixes from power domain names
- Rebase on top of Russell's changes to dwmac
- Rebase on top of even more changes from Russell that are not yet
in next (E1vB6ld-0000000BIPy-2Qi4@...-PC.armlinux.org.uk)
- Link to v2: https://lore.kernel.org/all/20251008-qcom-sa8255p-emac-v2-0-92bc29309fce@linaro.org/
Changes in v2:
- Fix the power-domains property in DT bindings
- Rework the DT bindings example
- Drop the DTS patch, it will go upstream separately
- Link to v1: https://lore.kernel.org/r/20250910-qcom-sa8255p-emac-v1-0-32a79cf1e668@linaro.org
