Hi, Geoff
You can find the patches you need here:
If you can check it in 'git log', you can easily track down to these basic topic branches. Each of them is on pure v4.4. And for a minimum system, you need:
working-hikey-tracking-dts-v4.4
working-hikey-tracking-config-v4.4 (, from it, pick those relate to you).
working-hikey-tracking-pmic-v4.4 (could be optional too. since by default bootloader already enables regulators for you)
BTW, I bet you know where to download UEFI for hikey.
== FYI,:
