The Linux device tree for the Allwinner A64 SoC has changed a lot since the U-Boot version was merged. Let's replace the current DT with a exact copy of the Linux one as of: commit c6778ff813d2ca3e3c8733c87dc8b6831a64578b Merge: 0ff4c01 3c0e3abd Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Tue May 9 10:07:33 2017 -0700 This is the DT used in Linux 4.12-rc1. Since U-Boot has an Ethernet driver (while Linux does not yet), we provide the required DT nodes for it in an ...-u-boot.dtsi file, to both mark them as U-Boot specific and to allow easier upgrading once Linux gets the driver and its own binding later. Compared to the existing Ethernet DT nodes we just slightly tweak the clock and reset nodes in there to match the new bindings used by Linux for those.
