To register other I2C controllers in the DTB:

  1. Locate the platform DTB in:
    
<top>/drive-foundation/firmware
/src/bootloader/quickboot/qb-t23x-partner
/data_driven/
  2. Add the I2C controller in the I2C DTB node.
  3. Add the corresponding I2C controller details in the Clock node to configure Clocks for the Controller.

    A sample command for using I2C is provided in core/console.c. Use it by enabling the interactive mode of the Quickboot.
