Changing the card voltage on the p200 is not instantaneous, especially
when switching from 3.3v to 1.8v.

I take at least 70ms for the regulator to go from 3.3v to 1.8v. Add
margin to that to make sure we don't upset the sdcard during the voltage
switch

Contrary to popular belief, PPIs connected to a GICv3 to not have
an affinity field similar to that of GICv2. That is consistent
with the fact that GICv3 is designed to accomodate thousands of
CPUs, and fitting them as a bitmap in a byte is... difficult.

As I found by chance while merging another patch, the usage of
a dma-mask in this DT node is wrong for multiple reasons:

- dma-masks are a Linux specific concept, not a general
  hardware feature
- In DT, we use the "dma-ranges" property to describe how DMA
  addresses related between devices.
- The 40-bit mask appears to be completely unnecessary here, as
  the SoC cannot address that much memory anyway, so simply
  asking for a 64-bit mask (as supported by the device) should
  succeed anyway.

The patch to remove the parsing of the property is getting merged
through the crypto tree.

Enable gpio support for CP and AP on the Marvell Armada 7K/8K SoCs.

The Armada 8K has two CP110 blocks, each having two GPIO controllers.
However, in each CP110 block, one of the GPIO controller cannot be
used: in the master CP110, only the second GPIO controller can be used,
while on the slave CP110, only the first GPIO controller can be used.

On the other side, the Armada 7K has only one CP110, but both its GPIO
controllers can be used.

For this reason, the GPIO controllers are marked as "disabled" in the
armada-cp110-master.dtsi and armada-cp110-slave.dtsi files, and only
enabled in the per-SoC dtsi files.
