72a5cf147d ARM: dts: overo: Add LIS33DE accelerometer
The LIS33DE accelerometer is used on several Gumstix expansion boards,
thus add the DT node to omap3-overo-common-peripherals.dtsi.

For the boards that do not have the accelerometer (like Tobi), mark the
status as disabled.

385306cc3e ARM: dts: overo: Create a file for common Gumstix peripherals
Gumstix expansion boards share a couple of peripherals:
- uart3 is used for the console
- AT24C01 EEPROM on i2c3

Use this file for overo-tobi.

1afb89746c ARM: dts: overo: Push uart3 pinmux down to expansion board
UART3 is used by expansion boards to get a tty console. Thus, the
pinmux should be defined by expansion boards, instead of being
imposed by the processor board.

c3fba2d05b ARM: dts: omap3-tobi: Use include file omap-gpmc-smsc9221
Use the timings provided by omap-gpmc-smsc9221. This does not change
the timings, but it avoids code duplication.

af3c0380eb ARM: dts: overo: reorganize include files
Currently, overo-related include files are organized as follow:

                     omap3-overo.dtsi
                             |
                             |
omap34xx.dtsi   omap3-overo-tobi-common.dtsi   omap36xx.dtsi
      |              |                 |             |
      ---------------                  ---------------
              |                                |
    omap3-overo-tobi.dts          omap3-overo-storm-tobi.dts

This is unpractical when one has to deal with SoC-specific pinmux
belonging to the omap3_pmx_core2 (defined in omap34xx/omap36xx),
for pins related to the processor board. With the current
hierarchy, such pinmux has to be defined in the expansion board's
.dts, which is not logical.

This patches reorganizes the files to add (yet another) abstraction
layer between the processor and the expansion boards.

omap34xx.dtsi       omap3-overo-base.dtsi      omap36xx.dtsi

f03ef09b6f ARM: dts: Add support for both OMAP35xx and OMAP36xx Overo/Tobi
Unfortunatly the device tree for older OMAP35xx Overo cannot be used
with newer OMAP36xx and vice-versa. To address this issue, move most of
the Tobi DTS to a common include file, and create model-specific Tobi
DTS.
