The CSI-2 spec defines format identifier for Data Type (DT), and how the Decode Format (DF) & Encode Format (EF) are implemented. The spec does however not define the DF, EF or Plain Format (PF) identifiers, as those are vendor specific. Plain formats describe the size of the pixels written by the RDI units to memory. PLAIN8 for example has the size 8 bits, and PLAIN32 32 bits. The appropriate Plain Format is determined by the Decode Format used. The smallest Plain Format that is able to contain a pixel of the used Decode Format is the appropriate one to use. As the vendor specific identifiers differ between hardware generations, split them out into separate headers.
