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.

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.

Benoit

No I have not updated, I will send a separate patch by adding all the supported
devices, missed from earlier (this device, tmp275 and lis331dlh)
