-title: MCTP I2C transport binding
-
-maintainers:
- - Matt Johnston <matt@codeconstruct.com.au>
-
-description: |
- An mctp-i2c-controller defines a local MCTP endpoint on an I2C controller.
- MCTP I2C is specified by DMTF DSP0237.
-
- An mctp-i2c-controller must be attached to an I2C adapter which supports
- slave functionality. I2C busses (either directly or as subordinate mux
- busses) are attached to the mctp-i2c-controller with a 'mctp-controller'
- property on each used bus. Each mctp-controller I2C bus will be presented
- to the host system as a separate MCTP I2C instance.
