+description: |
+  This is device node for the Parallel Camera Interface which enables the
+  chip to connect directly to external Parallel CMOS image sensors.
+  Supports up to 80MHz input clock from sensor.
+  Supports the following input data formats
+    - 8-bit/10-bit Camera Sensor Interface (CSI)
+    - 8-bit data port for RGB, YCbCr, and YUV data input
+    - 8-bit/10-bit data ports for Bayer data input
+  Parallel Camera Interface is hooked to the Imaging subsystem via the
+  Pixel Link.
