ARM: dts: overo: Add new expansion boards

Quoted 27 lines · Florian Vaussard

Hi,

This series adds the support for 5 new expansion boards from Gumstix:
- Palo43
- Gallop43
- Chestnut43
- Alto35
- Summit

The 1st patch is a preparatory work, in order to factorize some peripherals that are common to most Gumstix expansion boards. Patch 2 adds the support for an accelerometer that is present on most boards.

Palo43, Gallop43 and Chestnut43 are all pretty similar. I tested on a Gallop43 (with both OMAP35xx and OMAP36xx Overo).

Alto35 is slightly different. Again, I tested with both OMAP35xx and OMAP36xx Overo.

Summit is pretty similar to Tobi. I do not have a Summit at hand, but given the similarity with Tobi, it should work fine.

To avoid unnecessary duplications, I put all the common stuff for each board inside an omap3-overo-xxx-common.dsti include file. By doing so, I can have minimal SoC-specific omap3-overo-xxx.dts (omap34xx based) and omap3-overo-storm-xxx.dts (omap36xx based) device trees.

This series depends on my previous Overo series [1]. A complete testing tree (including the graphics support, soon to be posted) is available at [2].

Thanks, applying the whole series into omap-for-v3.15/dt-overo. As it's this close to the merge window, no guarantees anything will get pulled in though.
