[PATCH v2 0/4] ARM: dts: Fixes for Overo/Tobi against 3.14-rc2

[PATCH v2 0/4] ARM: dts: Fixes for Overo/Tobi against 3.14-rc2

[Florian Vaussard]

OMAP36xx-based Overo (Storm and alike) are now failing to boot with 3.14-rc2 [1].
This series fixes this, by moving model-agnostic DT into a common dtsi file,
and creating model-specific DT files:

- omap3-overo-tobi.dts -> older OMAP35xx Overo
- omap3-overo-storm-tobi.dts -> newer OMAP36xx/AM37xx/DM37xx Overo

People will have to use the right Overo / expansion board combination.

(Patch 2 in an unrelated fix that was waiting in my queue.)

omap3-overo-tobi.dts tested with Overo Sand (OMAP3503) and omap3-overo-storm-tobi.dts
tested with Overo EarthStorm (AM3703). Both boot. With the Overo Sand, I cannot
mount the ext3 rootfs, but this seems unrelated to the current topic, maybe
a missing errata.

Regards,
Florian

Changes since v1:
- Add "ti,omap3430" as a compatible string for OMAP35xx-based Overo
- Update the DT documentation to silence out checkpatch warnings (patch 4)

[PATCH v2 1/4] ARM: dts: omap3-tobi: Fix boot with OMAP36xx-based Overo

[Florian Vaussard]

Tobi expansion board can be used with both OMAP35xx-based Overo,
and OMAP36xx-based Overo. Currently the boot is broken with newer
OMAP36xx-based Overo (Storm and alike). Fix include file and
compatible string to be able to boot newer models.

This will break older models. This will be addressed later.

[PATCH v2 3/4] ARM: dts: Add support for both OMAP35xx and OMAP36xx Overo/Tobi

[Florian Vaussard]

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.

omap3-overo-storm-tobi.dts is not covered here, so, I wonder as the
number of boards supported keep increasing, is'nt it better we drop
the board information from omap.txt?
