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

properties:
  compatible:
    const: mipi-i3c-hci
  reg:
    maxItems: 1
  interrupts:
    maxItems: 1

required:
  - compatible
  - reg
  - interrupts

additionalProperties: false

examples:
  - |
    i3c@a0000000 {
      compatible = "mipi-i3c-hci";
      reg = <0xa0000000 0x2000>;
      interrupts = <89>;
    };
