/**
* DOC : overview
*
* Output Pipe Timing Combiner ( OPTC ) includes two major functional blocks :
* Output Data Mapper ( ODM ) and Output Timing Generator ( OTG ) .
*
* - ODM : It is Output Data Mapping block . It can combine input data from
* multiple OPP data pipes into one single data stream or split data from one
* OPP data pipe into multiple data streams or just bypass OPP data to DIO .
* - OTG : It is Output Timing Generator . It generates display timing signals to
* drive the display output .
