The only difference seems to be that support of MIPI CSI through a connected MIPI CSI-2 bridge. Add a device node for it, and pinctrl nodes for the commonly used MCLK and 8-bit parallel interface. The property /omit-if-no-ref/ is added to the pinctrl nodes to keep the device tree blob size down if they are unused.
