Hi Boris,

Given the current state of the subsystem I think it might worth start to 
think how to expose the devices under /dev.
My initial thoughts are to do the same think as for i2c, expose the 
buses or the i3c_devices and use ioctl for private transfers. Some 
direct CCC commands can be sent through the /sys as you plan for SETNEWDA .

What do you think about this?

Best regards,
Vitor Soares
