/**
 * DOC: overview
 *
 * The Output Plane Processor (OPP) block groups have functions that format
 * pixel streams such that they are suitable for display at the display device.
 * The key functions contained in the OPP are:
 *
 * - Adaptive Backlight Modulation (ABM)
 * - Formatter (FMT) which provide pixel-by-pixel operations for format the
 *   incoming pixel stream.
 * - Output Buffer that provide pixel replication, and overlapping.
 * - Interface between MPC and OPTC.
 * - Clock and reset generation.
 * - CRC generation.
