When you say 'All the dtbs_check warnings', you mean *all* or just all
the mailbox ones. I read as the former, but I guess from the prior
paragraph and the links you are talking about, it's just mailbox
warnings.
Overall, this is what TI 32-bit warnings look like:
Processing (am3|am4|am5|dra|keystone|omap|compulab|logicpd|elpida|motorola-cpcap|twl|da|dm):
warnings: 60358
undocumented compat: 3195
This comes from my CI job[1]. The warnings aren't deduplicated, so 1
SoC warning expands to N board warnings. Only 3879 unique warnings. :)
The top warnings are:
arch/arm/boot/dts/(am3|am4|am5|dra|keystone|omap|compulab|logicpd|elpida|motorola-cpcap|twl|da|dm):60358:3879:3195
