Hi, Philippe Currently, I'm really confused about what usage STYLE of SPDX license identifier I should use for each type of file. could you point me where I can find the related document describing SPDX usage style for those files expected by the community in the future? I found more than one way STYLE of SPDX present at current code, for example as below. If there's no absolute definition for them, and then which way that is better? 1) for *.dts, applied with "// " at head or within " /* */ " not at head such as arch/arm/boot/dts/bcm953012hr.dts:2: *
