The RISC-V "b" (Bit-manipulation) extension was ratified in April 2024, much later than its component extensions zba/zbb/zbs (June 2021). 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. Acked-by Paul Walmsley in v1. Patch 2, 3 and 4 adds "b" after "c" in 3 different device tree files respectivly, 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].
