Good reason to move the vblank stuff in there, and maybe even > fold the crtc helpers into the main kms patch :-) The crtc patch is 2/10.

I'll merge them together. > -Daniel > > > + > > +static void xlnx_mode_config_init(struct drm_device *drm) > > +{ > > + struct xlnx_drm *xlnx_drm = drm->dev_private; > > + struct xlnx_crtc_helper *crtc = xlnx_drm->crtc;
