Recent updates to the device tree bindings [2] enforce that when all three component extensions are present, "b" must also be specified. Related discussion can also be found in [1]. Patch 1 clarifies the ISA spec version for canonical ordering in uabi.rst. It is a trivial update, but can help readers reference the correct document version. Patch 2 adds "b" after "c" in 3 device tree files (anlogic, sophgo and spacemit), fixing the related dtbs_check warnings. This patchset is based on top of linux-next, tag: next-20260109, and depends on [2].
