Hi, > I recommend reading the DT spec, chapter 2.3.1 "compatible": > https://github.com/devicetree-org/devicetree-specification/releases/download/v0.3/devicetree-specification-v0.3.pdf My point is more about, DT validation is not happy about this situation. For instance when I run dt-validate, do see following: /home/amit/work/kernel_work/linux/arch/arm64/boot/dts/actions/s700-cubieboard7.dt.yaml: mmc@e0210000: compatible: Additional items are not allowed ('actions,s700-mmc' was unexpected) and I am not sure if this is because DT and driver has different number of compatible strings. Thanks Amit
