I don't think changing this is right. First, 'ns16550' is what's documented in the DT spec (and ePAPR which it's based on). Second, these dts files are pretty mature/stable, so I'm less inclined to change them. AFAICT, this change either enables the fifo (which would be an untested change in behavior) or has no effect because the fifo is auto-detected. > Use the appropriate compatible string that is also consistent with ARM64 > Freescale boards and thus avoiding one special case in the binding schema. Well, that's annoying... Rob
