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 ARM: dts: omap3-overo: Add missing pinctrl ARM: dts: omap3-tobi: Add missing pinctrl ARM: dts: overo: reorganize include files Signed-off-by: Arnd Bergmann <arnd@arndb.de> Conflicts: arch/arm/boot/dts/omap3-overo.dtsi
