Merge tag 'omap-for-v3.15/dt-overo-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt

Updates to the .dts files to support more Gumstix boards.

These are sent separately from the rest of the .dts changes
as these depend on the fixes merged into v3.14-rc4, and
needed a bit more time to get updated on the fixes.

* tag 'omap-for-v3.15/dt-overo-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: dts: Add support for the Overo Summit
  ARM: dts: Add support for the Overo Chestnut43
  ARM: dts: Add support for the Overo Alto35
  ARM: dts: Add support for the Overo Gallop43
  ARM: dts: Add support for the Overo Palo43
  ARM: dts: overo: Add LIS33DE accelerometer
  ARM: dts: overo: Create a file for common Gumstix peripherals
  ARM: dts: overo: Push uart3 pinmux down to expansion board
  ARM: dts: omap3-tobi: Add AT24C01 EEPROM
  ARM: dts: omap3-tobi: Use include file omap-gpmc-smsc9221
  ARM: dts: omap: Add common file for SMSC9221
  ARM: dts: omap3-overo: Add HSUSB PHY
  ARM: dts: omap3-overo: Enable WiFi/BT combo
