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.
Signed-off-by: Stephen Warren <swarren@nvidia.com>
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.

Here we split the description of the external-bus@50000000 over

This patch adds a generic target for SPEAr3xx machines that can be configured

- PL011 UART
- PL061 GPIO
- PL110 CLCD
- SP805 WDT

- Synopsys DW ethernet
- ST FSMC-NAND

- ST SPEAR-KEYBOARD
- ST SPEAR-RTC

Other peripheral devices will follow in later patches.
This also removes IO_ADDRESS macro and creates 16 MB static mappings instead of
4K for individual peripherals. This is done to have efficient TLB lookup for any
I/O windows that are located closely together. ioremap() on this range will
