+ * The IC Resizer has a restriction that the output frame from the
+ * resizer must be 1024 or less in both width (pixels) and height
+ * (lines).
+ *
+ * The image converter attempts to split up a conversion when
+ * the desired output (converted) frame resolution exceeds the
+ * IC resizer limit of 1024 in either dimension.
+ *
+ * If either dimension of the output frame exceeds the limit, the
+ * dimension is split into 1, 2, or 4 equal stripes, for a maximum
+ * of 4*4 or 16 tiles. A conversion is then carried out for each
+ * tile (but taking care to pass the full frame stride length to
+ * the DMA channel's parameter memory!). IDMA double-buffering is used
+ * to convert each tile back-to-back when possible (see note below
+ * when double_buffering boolean is set).
+ *
+ * Note that the input frame must be split up into the same number
+ * of tiles as the output frame.
+ *
+ * FIXME: at this point there is no attempt to deal with visible seams
+ * at the tile boundaries when upscaling. The seams are caused by a reset
+ * of the bilinear upscale interpolation when starting a new tile. The
+ * seams are barely visible for small upscale factors, but become
+ * increasingly visible as the upscale factor gets larger, since more
+ * interpolated pixels get thrown out at the tile boundaries. A possilble
+ * fix might be to overlap tiles of different sizes, but this must be done
+ * while also maintaining the IDMAC dma buffer address alignment and 8x8 IRT
+ * alignment restrictions of each tile.
