   1 Texas Instruments DRA72x CAMERA ADAPTATION LAYER (CAL)
   2 ------------------------------------------------------
   3
   4 The Camera Adaptation Layer (CAL) is a key component for image capture
   5 applications. The capture module provides the system interface and the
   6 processing capability to connect CSI2 image-sensor modules to the
   7 DRA72x device.
   8
   9 Required properties:
  10 - compatible: must be "ti,dra72-cal"
  11 - reg:  CAL Top level, Receiver Core #0, Receiver Core #1 and Camera RX
  12         control address space
  13 - reg-names: cal_top, cal_rx_core0, cal_rx_core1, and camerrx_control
  14              registers
  15 - interrupts: should contain IRQ line for the CAL;
  16
  17 CAL supports 2 camera port nodes on MIPI bus. Each CSI2 camera port nodes
  18 should contain a 'port' child node with child 'endpoint' node. Please
  19 refer to the bindings defined in
  20 Documentation/devicetree/bindings/media/video-interfaces.txt.
