I thought we had discussed either @ the Linaro Dublin meet or the Linaro Amsterdam meet that changing upstream YAML would be feasible _if_ you could show there was no dependency on it - say u-boot, FreeBSD etc. I completely understand why you'd say for a UART definition its an ABI since quite likely another OS might consume the YAML but, I also think nobody but upstream Linux cares about this binding at all and our only actual user is upstream dtsi in Linux, which doesn't exist yet. --- bod
