As explained in the description text from trivial-devices.yaml: "This is a list of trivial I2C and SPI devices that have simple device tree bindings, consisting only of a compatible field, an address and possibly an interrupt line." A camera device does not fall into this category as it needs other properties such as regulators, reset and powerdown GPIOs, clocks, media endpoint. Remove the OV5642 entry from trivial-devices.yaml and add its own ovti,ov5642.yaml.
