Hi,
in the wake of the sunxi DM enablement series it became apparent that the current device tree files for the A64 SoC and its board are outdated.
Since Linux v4.10-rc1 there are now basic .dts files for the Allwinner A64 SoC and the Pine64 boards in the mainline kernel. Linux v4.11-rc1 added MMC and USB support. Because our preliminary device trees used in U-Boot differ significantly, let's update our copy with what's in the current Linus' master tree. Since in contrast to U-Boot the kernel still lacks support for Ethernet, we keep our preliminary nodes for that IP, but adjust it slightly to match the new clocks and reset bindings.
As the sun8i-emac driver is actually using the DT for the pinmux setup, we teach it how to cope with the new pinctrl bindings in the first two patches. This is probably becoming somewhat obsolete very soon (with DM GPIO support on the list already), however I consider these two patches as merely fixes for the existing driver to maintain bisectability. It would make sense to merge the new DTs before the DM patches, so we need to have something in place which works meanwhile.
Let me know what you think.
Cheers, Andre.
