According to the device's datasheet, it can support an interrupt too.
However, the existing board file doesn't specify an interrupt, and I
don't have the schematics, so I can't add an interrupts property. The
current Linux driver doesn't support anyway.

The I2C2 controller can be routed to either pingroup DDC or PTA. Seaboard
actually uses this as an I2C bus mux, and devices are connected to both
pingroups. This change statically assigns the I2C2 controller to pingroup
PTA, so that on-board devices can be accessed. The DDC pingroup is used
for EDID/DDC accesses which are not yet required, given the absence of
any Tegra graphics support. I2C muxing will be supported later.

Ensure that the USB ULPI signals are not tri-stated, and have no pull-
up or pull-down.

Ensure that the pingroup hosting the USB ULPI reset signal (GPIO PV0 or
PV1 depending on the board, so UAC) is not tri-stated, and has no pull-
up or pull-down.

This change appears larger than it is due to the grouping and sorting of
the pin configuration data.

ULPI PHYs have a reset signal, and different boards use a different GPIO
for this task. Add a property to device tree to represent this.

I'm not sure if adding this property to the EHCI controller node is
entirely correct; perhaps eventually we should have explicit separate
nodes for the various PHYs. However, we don't have that right now, so this
binding seems like a reasonable choice.

These were incorrectly introduced and can cause problems for of_irq_init.

The correct way to define a root controller is no interrupt-parent set at

This patch adds a generic target for SPEAr600 board that can be
configured via the device-tree. Currently the following devices
are supported via the devicetree:

- VIC interrupts
- PL011 UART
- PL061 GPIO
- Synopsys DW I2C
- Synopsys DW ethernet

Other peripheral devices (e.g. SMI flash, FSMC NAND flash etc) will
follow in later patches.

Only the spear600-evb is currently supported. Other SPEAr600
based boards will follow later.

Since the current mainline SPEAr600 code only supports the SPEAr600
evaluation board, with nearly zero peripheral devices (only UART
and GPIO), it makes sense to switch over to DT based configuration
completely now. So this patch also removes all non-DT stuff, mainly
platform device data. The files spear600.c and spear600_evb.c are
removed completely.

This adds all devices that are normally present through the
u8500_init_machine function in the device tree as well, which
will duplicate the devices that are visible.

This will not do much by itself because the device from the
device tree are not matched by any device driver until they
are converted as well. The next step is to move over one
device at a time to actually be used from the device tree
instead of the hardcoded device using auxdata to pass the
correct platform_data.
