Merge tag 'staging-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 

Pull staging tree merge from Greg KH:
 "Here's the bit staging tree pull request for 3.12-rc1.

  Lots of staging driver updates, and fixes.  Lustre is finally enabled
  in the build, and lots of cleanup started happening in it.  There's a
  new wireless driver in here, and 2 new TTY drivers, which cause the
  overall lines added/removed to be quite large on the "added" side.

  The IIO driver updates are also coming through here, as they are tied
  to the staging iio drivers"

* Bosch BMA180 triaxial acceleration sensor



http://omapworld.com/BMA180_111_1002839.pdf



Required properties:



  - compatible : should be "bosch,bma180"

  - reg : the I2C address of the sensor



Optional properties:



  - interrupt-parent : should be the phandle for the interrupt controller



  - interrupts : interrupt mapping for GPIO IRQ, it should by configured with

		flags IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING



Example:



bma180@40 {

	compatible = "bosch,bma180";

	reg = <0x40>;

	interrupt-parent = <&gpio6>;

	interrupts = <18 (IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING)>;
