Your issue could be related with your dts configuration, please double check it and only include the ones you are using. 

In your log there is a warning: ERROR: invalid device tree 

Please use the one for the LX2160ARDB as reference:

Please also check your RCW, in the last one you shared there is a mistake 

The value of those field to use them as IIC is 0b000.

Hello,

Please share the RCW configuration you are using, also test the I2C first on u-boot and share the complete log file in a .txt format.

Are you using the BSP ? what version?
