That is what I do, I however do not want mips-next to have errors when
running dtbs_check. Having dtbs_check return errors is not an issue?

I shouldn't have called that a conflict, more like a dependency.

Yes, this series depends on "dt-bindings: hwmon: add common properties"
which the bot doesn't know it needs to apply.

Should I submit this patch independently and have my DTS be broken wrt
dtbs_check?

Have a nice day,
