This will conflict with a similar patch I have in drm-intel-next to unify the various bits of code that were attempting to modify the BLC PWM, each in their own unique fashion. I'll respin this native interface on top of that. Do you want to add a native RAW interface all in one go, or to base it on the current backlight_device and then to add the RAW property with this patch set? -Chris -- Chris Wilson, Intel Open Source Technology Centre
