13   CSI2DC - Camera Serial Interface 2 Demux Controller
15   CSI2DC is a hardware block that receives incoming data from either from an
17   It filters IDI packets based on their data type and virtual channel
20   controller.
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
26   is connected at the output to a sensor controller and the data pipe is
27   accessible as a DMA slave port to a DMA controller.

37   CSI2DC also supports direct access to the data through AHB, via DMA channel,
38   called data pipe.
39   For data pipe to be available, a dma controller and a dma channel must be

61       is also a clock source. This clock is named 'scck', sensor controller clock.
