CAL supports 2 line skipping read patterns. Those are mainly intended to provide vertically sub-sampled images. SW shall adjust the SDRAM start address to select the correct sub-sampled phase (that is, +0 and +2 lines in RD2SKIP2 mode; and +0, +2 and +4 lines in RD2SKIP4 mode). CAL_RD_DMA_YSIZE indicates the number of lines to read from SDRAM. It does therefore not include skipped lines.
