During driver probe, camss_parse_endpoint_node() in drivers/media/platform/qcom/camss/camss.c calls v4l2_fwnode_endpoint_parse() on each port@[0-5] endpoint. When bus-type is omitted and data-lanes is absent, v4l2_fwnode_endpoint_parse() does not detect a CSI-2 D-PHY bus and camss_parse_endpoint_node() fails with -EINVAL. Even when bus-type is explicitly set to D-PHY (4), omitting data-lanes leaves lncfg->num_data as = 0, causing csiphy_stream_on() in drivers/media/platform/qcom/camss/camss-csiph= y.c to fail phy_mipi_dphy_get_default_config_for_hsclk() with -EINVAL.

The first reg entry (top) is at 0x0900b000, while 0x09253000 is the second reg entry (csid0). Running make dt_binding_check triggers a dtc simple_bus_reg warning when the node unit-address does not match the first reg address.
