Thierry Reding 2388693e10 drm/sti: Use drm_crtc_vblank_*() API 
Non-legacy drivers should only use this API to allow per-CRTC data to be

Benjamin Gaignard f2cb314864 drm: sti: add VTG driver 
Video Time Generator drivers are used to synchronize the compositor
and tvout hardware IPs by providing line count, sample count,
synchronization signals (HSYNC, VSYNC) and top and bottom fields
indication.
VTG are used by pair for each data path (main or auxiliary)
one for master and one for slave.
