Did you forget to update the compatible string to ti,da850-vpif-capture?

+The TI Video Port InterFace (VPIF) capture component is the primary
+component for video capture on the DA850 family of TI DaVinci SoCs.
+
+TI Document number reference: SPRUH82C
+
+Required properties:
+- compatible: must be "ti,da850-vpif-capture"
+- reg: physical base address and length of the registers set for the device;
+- interrupts: should contain IRQ line for the VPIF
+
+VPIF capture has a 16-bit parallel bus input, supporting 2 8-bit
+channels or a single 16-bit channel.  It should contain at least one
+port child node with child 'endpoint' node. Please refer to the
+bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example using 2 8-bit input channels, one of which is connected to an
+I2C-connected TVP5147 decoder:
