Thanks, it compiles here fine too.

and while booting I'm now getting as with 3.9-rc:
[    0.409729] OMAP DSS rev 2.0
[    0.410980] omapdss DPI error: can't get VDDS_DSI regulator
[    0.410980] omapdss DPI error: device ips-056t init failed: -517

But here with linux-next (in contrast to 3.9-rc) removing all regulator
dependencies from drivers/video/omap2/dss/dpi.c does not make the trick.
The display stays dark :-( ...

 Thanks
