Poirier https://bugs.launchpad.net/bugs/630885 When booting, the omapdss subsystem is looking for a regulator named "vdds_sdi". When the regulator is not found the initialisation sequence is aborted resulting in omapfb not finding a display to work with. This patch allows the omapfb sub system to complete its initialisation properly and enable LCD display. The problem was fixed by lumping a "vdds_sdi" with the already existing "vdds_dsi" regulator. This fix takes its root from work done on the Beagle board and the Pandora board.
