title: MIPI CSI-2 Receiver core in the i.MX SoC

description:
  This is the device node for the MIPI CSI-2 Receiver core in the i.MX
  SoC. This is a Synopsys Designware MIPI CSI-2 host controller core
  combined with a D-PHY core mixed into the same register block. In
  addition this device consists of an i.MX-specific "CSI2IPU gasket"
  glue logic, also controlled from the same register block. The CSI2IPU
  gasket demultiplexes the four virtual channel streams from the host
  controller's 32-bit output image bus onto four 16-bit parallel busses
  to the i.MX IPU CSIs.
