+
+description: |
+ The Image Sensing Interface (ISI) combines image processing pipelines with
+ DMA engines to process and capture frames originating from a variety of
+ sources. The inputs to the ISI go through Pixel Link interfaces, and their
+ number and nature is SoC-dependent. They cover both capture interfaces (MIPI
+ CSI-2 RX, HDMI RX, ...) and display engine outputs for writeback support.
