However, family compatibles like "ti,am33xx" that came in before this was enforced are grandfathered. Ideally, the newly introced board/som specific strings should not propagate that wildcard. i.e. something like "phytec,am3352-phycore-som" or whatever is the base family part on these SOMs. -Matt > + > + aliases { > + rtc0 = &i2c_rtc;
