This patch set updates the latest device trees for Allwinner A64 based boards from Linux. In contrast to v1 I now took the actual 4.13-rc1 DTs from Linux, which restructures the patch set a bit.
The big advantage of having the very same DTs in U-Boot is that we can use UEFI boot much more easily, because U-Boot can just pass on its own DT, without having to find and load some external version. This makes UEFI based installers boot out of the box, which is a big relief. Linux 4.13-rc1 saw the addition of the sun8i-emac Ethernet driver, for which U-Boot has a driver for quite a while, but with a slightly different binding, so this series makes it compatible. Patch 1/6 adds some missing compatible strings, it was on the list before, but I add it to this series because it is a prerequisite for the following patches. Patches 2 till 4 add some code to be able to parse the new pinctrl bindings that newer Allwinner DTs use. Patch 5 extends U-Boot sun8i-emac driver to be able to properly parse the DT binding used by the new Linux driver as well. Patch 6 then actually replaces the DTs for A64 boards with the exact version as of the Linux tree (v4.13-rc1). This allows us to *almost* get rid of out *-u-boot.dtsi kludge, but we still need the alias, which the Linux version doesn't have, so this file still contains this one line, effectively.
I am still not convinced that having a full featured pinctrl driver in U-Boot is the right thing, so I cheekily ignore this part of the comments. If people consider this a requirement, we can have a look at this, but I don't see any reply since the first patch was posted some months ago, so I guess this takes much more time.
Also my apologies for not having looked at the syscon driver change Simon asked. It looks like a reasonable change, but I am about to leave for holidays and didn't want to postpone an updated version any longer.
Cheers, Andre.

This series look OK, to me. Will test emac and update. Meanwhile any comments please let me know.
thanks!
