[PATCH 0/2] ARM: omap/dts: Add support for Gumstix Overo with Tobi expansion

[PATCH 0/2] ARM: omap/dts: Add support for Gumstix Overo with Tobi expansion

[Florian Vaussard]

The Gumstix Overo is a computer on module using an OMAP3 processor.
This module must be plugged into an expansion board.

This patchset adds a first device tree support for the Overo, using the
Tobi expansion board. The current support is able to boot and mount
the rootfs from MMC, with a few extra features.

The first patch creates the device tree for both the Overo and the
Tobi expansion board, and updates the dtb build target.

The second patch updates the omap/dts documentation.

This patchset applies on tony's tree [1], devel-dt branch.

Regards,

Florian

[PATCH 1/2] ARM: omap/dts: Add support for Gumstix Overo with Tobi expansion board

[Florian Vaussard]

The Gumstix Overo is a computer on module using an OMAP3 processor.
This module must be plugged into an expansion board.

This patch adds a first device tree support for the Overo, using the
Tobi expansion board. The current support is able to boot and mount
the rootfs from MMC.

This patche also updates the omap3 dtb build target.

Currently working:
- mmc0 (on board microSD)
- i2c0 and i2c2 (i2c1 not used)
- led on GPIO

Great, I'm assuming Benoit will pick this up as well.

Patches looks good to me. I just adding them right now in my for_3.7/dts tree.

I've just slightly changed the subjects:

Documentation: dt: Update the OMAP documentation with Overo/Toby
ARM: dts: OMAP3: Add support for Gumstix Overo with Tobi expansion board

If you want to give it a try, here is the branch that contains all the DTS series I
already pulled. It includes your gpio-twl4030 patches as well.

git://git.kernel.org/pub/scm/linux/kernel/git/bcousson/linux-omap-dt.git for_3.7/dts

Regards,
Benoit

Great, thank you! I will test your branch on my Overo ASAP.

Boot as expected on Gumstix Overo with Tobi expansion board.

I will submit a patch to support the blue LED connected to the TWL4030, 
as the DTS support was merged in your branch.

And of course I will continue on getting features to work with 
devicetree for the Overo.

Regards,
Florian
