Seems there's a patch from Denis Carikli for this, which will probably be merged for 3.15. I realized I don't actually use panel-dpi at the moment in my OMAP DSS DT series, as I dropped the board changes that used panel-dpi. So I'll drop panel-dpi bindings from my series, and the backlight for panel-dpi can then be fixed for 3.16. Tomi -------------- next part -------------- A non-text attachment was scrubbed...
