Bug Description

SRU:

BUG:

due to a clash between upstream hdmi detection handling and the TI BSP, hdmi video out was broken.

IMPACT:

we din't have any canonical video output, and people were thought the board was stuck

FIX:

in Ubuntu-3.2.0-1412.15 upstream hdmi code was correctly merged with TI code.

---------

The latest ubuntu-desktop image (20120323) fails to show video out. This report was generated from the ubuntu-server daily image so that login was possible via serial console.
