Some are not addressed as they were false positives (nothing in the PHY driver ever calls phy_runtime_get() on the parent device) or I decided they make no sense - like the suggestion to remove the power-domain-names property because there's only one power domain. -- 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 Signed-off-by: Bartosz Golaszewski --- Changes in v15: - Squash patches 6 and 7 to avoid a potential hang-on-resume regression (Sashiko) - Fix the AUTONEG_DISABLE early return path in forced mode (Sashiko) -
