13   CSI2DC - Camera Serial Interface 2 Demux Controller
15   CSI2DC is a hardware block that receives incoming data from either from an
22   CSI2DC can act a simple bypass bridge if the incoming data is coming from
25   CSI2DC provides two pipes, one video pipe and one data pipe. Video pipe
29   CSI2DC supports a single 'port' node as a sink port with either Synopsys
30   32-bit IDI interface or a parallel interface.
32   CSI2DC supports one 'port' node as source port with parallel interface.
37   CSI2DC also supports direct access to the data through AHB, via DMA channel,

55       CSI2DC must have two clocks to function correctly. One clock is the
