7 title: MCTP I2C transport
10 - Matt Johnston <matt@codeconstruct.com.au>
13 An mctp-i2c-controller defines a local MCTP endpoint on an I2C controller.
14 MCTP I2C is specified by DMTF DSP0237.
16 An mctp-i2c-controller must be attached to an I2C adapter which supports
18 busses) are attached to the mctp-i2c-controller with a 'mctp-controller'

11 This driver provides an MCTP-over-serial interface, through a
12 serial line-discipline, as defined by DMTF specification "DSP0253 -
13 MCTP Serial Transport Binding". By attaching the ldisc to a serial
14 device, we get a new net device to transport MCTP packets.
16 This allows communication with external MCTP endpoints which use
