Hi,
This series enables the DVI and LCD panels 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.
This series depends on several patches from Tomi [1][2][3] targeting 3.16.
Regards,
Florian
Since v1:
- Rebased on 3.15-rc4 + recent patches from Tomi
[1] http://thread.gmane.org/gmane.linux.ports.arm.omap/114572
[2] http://thread.gmane.org/gmane.linux.ports.arm.omap/114560

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

use it on relevant expansion boards.
