dt-bindings: i3c: MIPI I3C Host Controller Interface
The MIPI I3C HCI (Host Controller Interface) specification defines a common software driver interface to support compliant MIPI I3C host controller hardware implementations from multiple vendors. All that is needed is an I/O area and an interrupt signal;. The hardware is self-advertising wrt its implementor and implemented capabilities so there is currently no details that the driver can't figure out on its own.

+ MIPI I3C Host Controller Interface
+
+ The MIPI I3C HCI (Host Controller Interface) specification defines
+ a common software driver interface to support compliant MIPI I3C
+ host controller hardware implementations from multiple vendors.
+
+ The hardware is self-advertising for differences in implementation
+ capabilities, including the spec version it is based on, so there
+ isn't much to describe here (yet).
+
+ For details, please see:
+ https://www.mipi.org/specifications/i3c-hci
