/**
 * DOC: overview
 *
 * Multiple Pipe/Plane Combiner (MPC) is a component in the hardware pipeline
 * that performs blending of multiple planes, using global and per-pixel alpha.
 * It also performs post-blending color correction operations according to the
 * hardware capabilities, such as color transformation matrix and gamma 1D and
 * 3D LUT.
 *
 * MPC receives output from all DPP pipes and combines them to multiple outputs
 * supporting "M MPC inputs -> N MPC outputs" flexible composition
 * architecture. It features:
 *
 * - Programmable blending structure to allow software controlled blending and
 *   cascading;
 * - Programmable window location of each DPP in active region of display;
 * - Combining multiple DPP pipes in one active region when a single DPP pipe
 *   cannot process very large surface;
 * - Combining multiple DPP from different SLS with blending;
 * - Stereo formats from single DPP in top-bottom or side-by-side modes;
 * - Stereo formats from 2 DPPs;
 * - Alpha blending of multiple layers from different DPP pipes;
 * - Programmable background color;
