7 title: I3C bus
14   I3C busses can be described with a node for the primary I3C controller device
15   and a set of child nodes for each I2C or I3C slave on the bus. Each of them
20     pattern: "^i3c@[0-9a-f]+$"
27       All I3C devices are supposed to support DAA (Dynamic Address Assignment),
28       and are thus discoverable. So, by default, I3C devices do not have to be
32       I3C devices.
34       Another use case for describing an I3C device in the device tree is when
35       this I3C device has a static I2C address and we want to assign it a
36       specific I3C dynamic address before the DAA takes place (so that other
42   i3c-scl-hz:
44       Frequency of the SCL signal used for I3C transfers. When undefined, the
62       MCTP over I3C transport.
