String instead of ms? No, this is the craziest idea I saw recently.

Nothing can bind to it, no usage explained. Properties are not used to "store the duration". This does not look like suitable for DT, drop entire binding. > + > +required: > + - pre-abl-time > + - abl-time > + > +additionalProperties: false > + > +examples: > + - | > + bootstats { > + pre-abl-time="17627"; > + abl-time="26748"; Missing spaces. Open existing DTS and look at existing coding style. Best regards, Krzysztof
