One just has to go look at AHCI, EHCI, OHCI, XHCI, UFS, 8250, etc. bindings. Let's not start with pretending that here. Fine for this to be a fallback, but it must have a compatible for a specific implementation. Also, which version of the spec does this compatible correspond to? Or are there not HCI differences in the spec versions you mention in the cover letter? > +- reg : Should contain 1 register range (address and length) > +- interrupts : HCI interrupt > + > +Example: > + > + mipi_i3c_hci@0xa0000000 { i3c@a0000000 > + compatible = "mipi-i3c-hci"; > + reg = <0xa0000000 0x2000>; > + interrupts = <89>; > + }; > -- > 2.26.2 >
