I found (via schema checks!) a couple of errors with stdout-path values: arch/arm/boot/dts/imx53-ppd.dts: stdout-path = "&uart1:115200n8"; arch/arm/boot/dts/vf610m4-colibri.dts: stdout-path = "&uart2"; Since they are quoted, there is no resolving the label ref to a path string. The second case is easily fixed by dropping the quotes. The first case is not other than switching to an alias. So should it be supported in some form? Perhaps a syntax like this: stdout-path = &uart1 ":115200n8"; If that's supported, then should this be: stdout-path = "/a/path/to/a/node" ":115200n8"; The downside to allowing this is a missing comma between 2 strings would no longer fail. Thoughts? Rob
