It's been told to me a few times that this kernel module
should not exist, instead we should use the loopback test
from userspace if need be. If a kernel module is required
for testing SPI, it should be generic and put in
drivers/spi/*.
Delete this driver.

Clearing obj-y, obj-m, obj-n, obj- in each Makefile is
a useless habit.
They are non-exported variables; therefore they are always empty
whenever descending into each subdirectory.
(Moreorver, obj-y and obj-m are also set to empty at the beginning
of scripts/Makefile.build)

Move the U300 timer driver down to the clocksource driver
subsystem and keep arch/arm clean.

We have now transferred all the U300 peripherals to the device
tree, so we just select USE_OF, and delete all static board data,
then require that this platform shall be booted using the device
tree and nothing else.
This gets rid of the MMCI (PL180), PL022, and serial PL011
platform data entries and more.

This gets rid of the separate u300.c file in mach-u300 since
it can just as well live right in core.c, then we also get
rid of the broadcasted <mach/platform.h> file that is not
helping anyone. Put the interface to the system timer into
a separate header.

This converts the U300 clock implementation over to use the common
struct clk and moves the implementation down into drivers/clk.
Since VCO isn't used in tree it was removed, it's not hard to
put it back in if need be.

All the special stuff (like registering input device and so on)
for the U300 MMC is now done away with. We don't need these
special MMC setup kludges, merge this into core.c and be done
with it.

This adds a driver for the U300 pinmux portions of the system
controller "SYSCON". It also serves as an example of how to use
the pinmux subsystem. This driver also houses the platform data
for the only supported platform.
This deletes the old U300 driver in arch/arm/mach-u300 and
replace it with a driver using the new subsystem.
The new driver is considerably fatter than the old one, but it
also registers all 467 pins of the system and adds the power
and EMIF pin groups and corresponding functions. The idea
is to use this driver as a a reference for other
implementation so it needs to be as complete and verbose
as possible.

This adds a U300 board configuration for the PL022 SSP/SPI
PrimeCell driver recently merged to the 2.6.31-rc series.
Further it adds a dummy loopback SPI chip that can be used
for testing the SPI functionality on a running system using
the loopback mode of PL022.

This adds core support for the ST-Ericsson U300 series
platforms: U300, U330, U335 and U365. Supports memory
mappings, interrupt controller, system timer (clocksource
and clockevents), and binds to the existing drivers for
the PrimeCells used in this design: PL190 (VIC), PL180
(MMC/SD host) and PL011 (UART). This is intented to serve
as starting point for our mainling work, more patches to
follow.
