Hi Inki, This patchset fixes long standing issue with occassional page faults or vblank event timeouts on TM2 targets due to delayed vblank handling. DECON driver should now handle properly all scenarios described in drm docs [1][2], at least it was my intention. The patchset also: - adds frame counter callback, - fixes VBLANK interrupt trigger time, - fixes soft-trigger mask, - removes redundant pipe related fields. The patch is based on todays linux-next, the real dependency is on the Shawn patchset 'Add vblank hooks to struct drm_crtc_funcs'. I have successfully tested it on TM2 panel, TV and both.
