title: i.MX8QM Image Sensing Interface

maintainers:

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.
