   14   In Tegra186 and later, the BPMP (Boot and Power Management Processor)
   15   owns certain HW devices, such as the I2C controller for the power
   16   management I2C bus. Software running on other CPUs must perform IPC to
   17   the BPMP in order to execute transactions on that I2C bus. This
   18   binding describes an I2C bus that is accessed in such a fashion.
   19 
   20   The BPMP I2C node must be located directly inside the main BPMP node.
   21   See ../firmware/nvidia,tegra186-bpmp.yaml for details of the BPMP
   22   binding.
   23 
   24   This node represents an I2C controller. See ../i2c/i2c.txt for details
   25   of the core I2C binding.
