+Texas Instruments DS90UB954-Q1 dual video deserializer
+======================================================
+
+The TI DS90UB954-Q1 is a MIPI CSI-2 video deserializer that forwards video
+streams from up to two FPD-Link 3 connections to a MIPI CSI-2 output. It
+also allows access to remote I2C and GPIO.
+
+Required properties:
+
+ - compatible: must be "ti,ds90ub954-q1"
+
+ - reg: main I2C slave address; optionally aliases for RX port registers
+   and remote serializers. The main address is mandatory and must be the
+   first, others are optional and fall back to defaults if not
+   specified. See "reg-names".
+
+ - reset-gpios: chip reset GPIO, active low (connected to PDB pin of the chip)
+ - i2c-alias-pool: list of I2C addresses that are known to be available on the
+                   "local" (SoC-to-deser) I2C bus; they will be picked at
+		   runtime and used as aliases to reach remove I2C chips
+ - gpio-controller
+ - #gpio-cells: must be 3: FPD-Link 3 RX port number, remote gpio number, flags
+
+Optional properties:
+
+ - reg-names: names of I2C address used to communicate with the chip, must
+              match the "reg" values; mandatory if there are 2 or more
+              addresses
+    - "main": the main I2C address, used to access shared registers
+    - "rxport0", "rxport1": I2C alias to access FPD-link RX port specific
+      registers; must not be used by other slaves on the same bus
+    - "ser0", "ser1": I2C alias to access the remote serializer connected
+      on each FPD-link RX port; must not be used by other slaves on the
+      same bus
+ - interrupts: interrupt pin from the chip
+
+Required subnodes:
+
+ - ports: A ports node with one port child node per device input and output
+          port, in accordance with the video interface bindings defined in
+          Documentation/devicetree/bindings/media/video-interfaces.txt. The
+          port nodes are numbered as follows:
+
+          Port Description
+          ------------------------------------
+          0    Input from FPD-Link 3 RX port 0
+          1    Input from FPD-Link 3 RX port 1
+          2    CSI-2 output
+
+          Each port must have a "remote-chip" subnode that defines the remote
+	  chip (serializer) with at least a "compatible" property
+
+ - i2c-atr: contains one child per RX port, each describes the I2C bus on
+            the remote side
+
+	    Required properties:
+	    - #address-cells = <1>;
+	    - #size-cells = <0>;
+
+	    Subnodes: one per each FPD-link RX port, each having:
+
+	    Required properties for "i2c-atr" child bus nodes:
+	    - reg: The number of the port where the remove chip is connected
+	    - #address-cells = <1>;
+	    - #size-cells = <0>;
+
+	    Optional properties for "i2c-atr" child bus nodes:
+	    - Other properties specific to the remote hardware
+	    - Child nodes conforming to i2c bus binding
+
