This patch series converts the davinci i2c driver to use device model. This updated driver has been verified on both Keystone K2G and Keystone K2L evms by performing several i2c operations in U-boot prompt.
Some additional work was required to get things working on K2G due to the code that reads the on board EEPROM. DM I2C sets the default address length to a default value of 1 when the on EEPROM requires an address length of 2. Therefore, an additional function and minor changes were required to get things working properly.
This series breaks boot in K2HK evm. Below is the log.

Can you please look at it.
Thanks and regards, Lokesh
