+Synopsys DesignWare CSI-2 Host controller
+
+Description
+-----------
+
+This HW block is used to receive image coming from an MIPI CSI-2 compatible
+camera.
+
+Required properties:
+- compatible: shall be "snps,dw-mipi-csi"
+- reg		: physical base address and size of the device memory mapped
+  registers;
+- interrupts	: CSI-2 Host interrupt
+- output-type   : Core output to be used (IPI-> 0 or IDI->1 or BOTH->2) These
+  values choose which of the Core outputs will be used, it can be Image Data
+  Interface or Image Pixel Interface.
+- phys: List of one PHY specifier (as defined in
+  Documentation/devicetree/bindings/phy/phy-bindings.txt). This PHY is a MIPI
+  DPHY working in RX mode.
+- resets: Reference to a reset controller (optional)
+
+Optional properties(if in IPI mode):
+- ipi-mode 	: Mode to be used when in IPI(Camera -> 0 or Controller -> 1)
+  This property defines if the controller will use the video timings available
+  in the video stream or if it will use pre-defined ones.
+- ipi-color-mode: Bus depth to be used in IPI (48 bits -> 0 or 16 bits -> 1)
+  This property defines the width of the IPI bus.
+- ipi-auto-flush: Data auto-flush (1 -> Yes or 0 -> No). This property defines
+  if the data is automatically flushed in each vsync or if this process is done
+  manually
+- virtual-channel: Virtual channel where data is present when in IPI mode. This
+  property chooses the virtual channel which IPI will use to retrieve the video
+  stream.
+
+The per-board settings:
+ - port sub-node describing a single endpoint connected to the camera as
+   described in video-interfaces.txt[1].
