		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

		compatible:
		const: mipi-i3c-hci

		reg = <0xa0000000 0x2000>;
