Hi,

This series enables the DVI / LCD graphics present on some of
the Overo expansion boards.

DVI output:
- Tobi
- Summit

LCD (3.5''):
- Alto35

LCD (4.3''):
- Chestnut43
- Palo43
- Gallop43

I tested on Tobi, Alto35 and Gallop43 using both OMAP35xx and OMAP36xx
Overo boards.

This series depends on Tomi's DSS patches [1] that are not yet merged.
It also depends on previous Overo series [2] and [3] that are under
review. A complete testing tree is available [4].

Regards,
Florian

Summit and Tobi expansion boards have a HDMI connector with a TFP410
encoder. Add a common include file for this configuration, and then
use it for Summit and Tobi.

Chestnut43, Gallop43 and Palo43 expansion boards have a ZIF connector
for a 4.3'' LCD.Add a common include file for this configuration, and
use it on relevant expansion boards.

* [PATCH 3/3] ARM: dts: overo: Add support for 3.5'' LCD output

Alto35 expansion board has a ZIF connector for a 3.5'' LCD.
Add a common include file for this configuration, and use it
on Alto35.

The i2c3 pins don't belong here, they are not related to dss. The
dvi-connector uses i2c3, but I don't think they belong there either, as
the i2c3 bus can be used by multiple devices. So I guess they should be
set in &i2c3 node.

Looks good to me. Unfortunately the video bindings are still being
