Compared to the last post, this converts U-Boot's DTs over to use the new binding, so that the final patch can remove support for the old binding from U-Boot EMAC driver. The Linux DTs can be synced in later once we solved the size problem.
================================================ The existing sun8i-emac driver in U-Boot uses some preliminary bindings, which matched our own DTs. Now that the Linux kernel got a driver, lets update our probe code to handle those Linux DTs as well. The first patch adds the missing compatible strings for the pinctrl drivers, which is needed for using the sunxi_name_to_gpio() lookup function. Patch 2/7 updates the pinctrl parser used in the sun8i-emac driver, to cope with the new, generic Allwinner pinctrl bindings. Patch 3/7 extends the probe routine in the Ethernet driver to deal with both the old and the new bindings. Patches 4, 5 and 6 update U-Boot's DTs for boards using the A64, H3 and H5 SoC, respectively, to actually use the new binding in their EMAC nodes. This allows the final patch 7/7 to remove the support for the old binding in the EMAC driver, so we use the proper binding only. This series allows to copy in the DTs from the latest kernel. Unfortunately right now updating the DTs for the H5 and A64 breaks the build, as the resulting binary (which embeds the DT) gets to large and triggers our new image size check. As the H5 and H3 share most of the DT, we can't just update the H3 DTs either.
Same case with me with USB PHY changes, better to check size by disabling dts changes on H5/A64 if OK, then will move this to next. Once FAT transition done we can take them back - this is what I'm thinking as of now.
