This patch configures the user LED on Snowball to double flash
every second or so, whilst it's still alive. This can give key
indications as to what the board is doing in the case of no
console output.

This patch enables and illuminates the user_led on the
Snowball low-cost development board using DT. It also
removes initialisation carried out from platform code.

Allow proper initialisation for MMC via the mmci driver
for the Snowball low-cost development board using DT. At
the moment we continue to use DMA setup from platform code.
Once the DMA generic DT bindings have been completed we
can then port the remainder over to DT.

Here we supply the information required to setup regulators successfully

This patch adds a fixed regulator for use by the SMSC911x Ethernet
chip driver into the db8500 Device Tree. It also references other
regulators required by the same device.

This patch applies the correct format requested by the irq
domain. For chained IRQs which use GPIO lines as IRQs, we
stipulate that a two cell request is required. The first cell
contains the requested IRQ and the second can contain flags
pertaining to edge detection and level sensitive values. The
zeroth cell specifies the GPIO controller by use of a phandle.

Here we split the description of the external-bus@50000000 over
two description files. In the more generic db8500 description file
we only specify the external-bus. Normally this would be used to
communicate with a NOR-flash device. On the Snowball however, the
SMSC9115 Ethernet chip occupies it. In the Snowball board specific
description file is where we actually specify that it is in fact the
Ethernet device which lives here.

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.

This provides very basic Device Tree support for ST-Ericsson's
low-cost development platform, Snowball. If Device Tree for
ux500 is enabled and the correct board is configured within the
Device Tree blob, the correct *_init_machine() will be called.
