+/**
+ * DOC: Video Input Unit
+ *
+ * VIU Handles the Pixel scanout and the basic Colorspace conversions
+ * We handle the following features :
+ *
+ * - OSD1 RGB565/RGB888/xRGB8888 scanout
+ * - RGB conversion to x/cb/cr
+ * - Progressive or Interlace buffer scanout
+ * - OSD1 Commit on Vsync
+ * - HDR OSD matrix for GXL/GXM
+ *
+ * What is missing :
+ *
+ * - BGR888/xBGR8888/BGRx8888/BGRx8888 modes
+ * - YUV4:2:2 Y0CbY1Cr scanout
+ * - Conversion to YUV 4:4:4 from 4:2:2 input
+ * - Colorkey Alpha matching
+ * - Big endian scanout
+ * - X/Y reverse scanout
+ * - Global alpha setup
+ * - OSD2 support, would need interlace switching on vsync
+ * - OSD1 full scaling to support TV overscan
