The first patch had been applied on mvebu/arm64-for-4.14.
Patch 2 to 6 had been applied on mvebu/dt64-for-4.14.
For the patch 4, I merged it with the patch that Thomas previously sent
because it was not in mainline yet even if it was on the backport
branch. The resulting patch is attached.

Subject: [PATCH] arm64: dts: marvell: fix USB3 regulator definition on
MacchiatoBin
Due to the lack of GPIO support, the USB3 regulator definition was
left unfinished in the MacchiatoBin DT description. Now that GPIO
support is available, this commit adjusts the Device Tree to properly
describe the USB3 regulator.

2.13.2
Finally I tested the last patch with an Ethernet PCIe card it worked
well, but the reset part was not tested as I don't know how it should be
tested.
As soon as the v4.13-rc1 will be released then the branches will be rebased
on it and renamed mvebu/arm64 and mvebu/dt64.
Thanks,
Gregory
