This driver implements the support for the PCIe interfaces on the
Marvell Armada 370/XP ARM SoCs. In the future, it might be extended to
cover earlier families of Marvell SoCs, such as Dove, Orion and
Kirkwood.

The driver implements the hw_pci operations needed by the core ARM PCI
code to setup PCI devices and get their corresponding IRQs, and the
pci_ops operations that are used by the PCI core to read/write the
configuration space of PCI devices.

Since the PCIe interfaces of Marvell SoCs are completely separate and
not linked together in a bus, this driver sets up an emulated PCI host
bridge, with one PCI-to-PCI bridge as child for each hardware PCIe
interface.

In addition, this driver enumerates the different PCIe slots, and for
those having a device plugged in, it sets up the necessary address
decoding windows, using the mvebu-mbus driver.

This driver requests and remaps a memory region as configured in the
device tree.  It serves memory from this region via the genalloc API.  It
optionally enables the SRAM clock.

Other drivers can retrieve the genalloc pool from a phandle pointing to
this drivers' device node in the device tree.

The allocation granularity is hard-coded to 32 bytes for now, to make the
SRAM driver useful for the 6502 remoteproc driver.  There is overhead for
bigger SRAMs, where only a much coarser allocation granularity is needed:
At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap
to track allocations.

This adds a complete DT binding for the arasan device driver. There is
currently only one user, which is the spear13xx platform, so we don't
actually have to parse all the properties until another user comes in,
but this does use the generic DMA binding to find the DMA channel.

The patch is untested so far and is part of a series to convert
the spear platform over to use the generic DMA binding, so it
should stay with the rest of the series.

The i2c-arb-gpio-challenge driver implements an I2C arbitration scheme
where masters need to claim the bus with a GPIO before they can start
a transaction.  This should generally only be used when standard I2C
multimaster isn't appropriate for some reason (errata/bugs).

This driver is based on code that Simon Glass added to the i2c-s3c2410
driver in the Chrome OS kernel 3.4 tree.  The current incarnation as a
mux driver is as suggested by Grant Likely.  See

 +               reg = <0x20>;
 +       };
 for SLB 9635 devices

to your device tree.
tpm_i2c_infineon is also retained as a compatible id as a fallback to
