[PATCH v5 08/22] media: camss: Add missing format identifiers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The CSI-2 spec defines the following types:
 - Data Type - Often abbreviated DT
 - Decode Format - Often abbreviated as DF
 - Encode Format

These definitions are as far as I can tell complete for CSI-2.

Additionally the Qualcomm internal type describing Plain Formats
has been added. 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.
