Have you updated the binding documentation to list the device? It should be in: Documentation/devicetree/bindings/i2c/trivial-devices.txt Please Cc as well the DT ml.

Add tsl2550 ambient light sensor DT data to am335x-evm.dts. In AM335x EVM tsl2550 ambient light sensor is connected to I2C2 bus. So this patch adds child node inside i2c2 node with i2c slave address. TAOS tsl2550 sensor with two-wire SMBus serial interface. This patch also reduces I2C2 clock frequency to 100KHz from 400KHz because the maximum clock frequency of SMBus is 100KHz.
