+ * DOC: Video Post Processing
+ *
* VPP Handles all the Post Processing after the Scanout from the VIU
* We handle the following post processings :
- * - Postblend : Blends the OSD1 only
+ *
+ * - Postblend, Blends the OSD1 only
* We exclude OSD2, VS1, VS1 and Preblend output
* - Vertical OSD Scaler for OSD1 only, we disable vertical scaler and
* use it only for interlace scanout
* - Intermediate FIFO with default Amlogic values
*
* What is missing :
+ *
* - Preblend for video overlay pre-scaling
* - OSD2 support for cursor framebuffer
* - Video pre-scaling before postblend
