As for Loongson64 all DTBs are built into kernel binary. So as long as binding are changed together with all DTS in tree we won't break any system. > As for the offending property, it has no place here either. DT is not > the place where you put "performance knobs". Hmm, I can see various bindings with vendor prefix exposing device configurations. If we seen this interrupt routing as a device configuration I don't think it's against devicetree design philosophy. Thanks - Jiaxun > > M. >
