[PATCH 0/1]: Acceleration threshold configuration

Howdy everyone!

Further accelerometer spamming. The patch in the next mail implements
an interface for setting a acceleration threshold for the input to keep
the freerunner-on-a-table quiet.

Some discussion points:

* I've based this on the bitbang-all-the-way-baby from the Andy branch.
  My experiments with spi_async() have not been very successful - I'm
  seeing missed interrupts just like with the "plain" workqueue
  implementation, but in this case it's actually harder to loop until
  the status is OK - the completion callback is called from a
  workqueue, so submitting other stuff (with reg_read()) isn't
  guaranteed to actually execute.

* This patch will break (the anyway non-working) acceleration wakeup
  implementation. However, I'm thinking that we should just change that
  to be set when the device is suspended anyway.

* I'd like some more testing of this patch!

* I'm slightly worried about the working hours for Andy, Werner and the
  others, don't you have 40h weeks at Openmoko? :-)

  (The last point *is* actually serious)
