> Changes done : > 1. Shared schema between host and embedded controller. 2. Commands messages are handled at driver level. 3. Debug message type added to enable debugging on i2c, spi and gpio's. 4. Auto test capabilities added to ethernet module. 5. Unit test cases written for multiple devices like LTC4275, LTC4274, LTC4015,ADT7481, PCA9557, SX1509.
