The Ethernet MAC used in newer Allwinner SoCs (H3, A64, H5) is about to get an upstream Linux driver very soon (it's already lurking in -next). To support the different binding used for that, enhance our U-Boot driver to be able to cope with both DT descriptions. This series contains two parts: Patch 1 and 2 make it easier for more A64 boards to use Ethernet, by renaming the existing sun50i-a64-pine64-plus-u-boot.dtsi add-on file to use a more generic name and symlinking each board to. This remains a kludge for now until the new Linux DT gets merged in. Patches 3 till 6 now enhance the DT parsing routine in the EMAC driver to teach it to cope with both the old and new style binding: - Allow the new pinctrl bindings. - Find the syscon address referenced by a phandle in "syscon". - Find the PHY node referenced by "phy-handle" (not just "phy"). - Adjust the syscon address according to the binding used. - Determine usage of the internal PHY by using the MII protocol.
So this series prepares U-Boot for merging in new Linux DTs later, which will describe the EMAC and PHY using the new binding instead. Cheers, Andre.
