[PATCH 1/2] arm64: dts: marvell: fix USB3 regulator definition on MacchiatoBin

[Thomas Petazzoni]

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.

[PATCH 2/2] arm64: defconfig: enable nop-xceiv PHY driver

[Thomas Petazzoni]

This commit enables the nop-xceiv PHY driver, which is needed for USB
support to work on the MacchiatoBin platform (Marvell Armada 8K).

If you weren't soo keen with your NIH patches, then you wouldn't be
making a mistake here...

Now, from what you've said on IRC, I know that you're more than happy
to fetch my git tree and test it on your board, and I've already stated
in a previous thread that I'm happy for people to take the DTS patches
I have in that branch, but still you persist in creating your own (and
in this case broken) patches.

While it _may_ work for you, it is not correct to the binding doc.

Now, you could have taken these three patches from my tree (which I
know you have from what you said on IRC):

  arm64: dts: marvell: mcbin: add GPIO
  arm64: dts: marvell: mcbin: add pinctrl nodes
  arm64: dts: marvell: mcbin: add gpio binding include file

which apply cleanly on top of arm-soc, and tested them with your gpio
and pinmux work.  In fact, these three patches are solving the exact
problem you have here.
