None, because the Marvell ones get these: 28 crypto@800000: interrupt-names:5: 'mem' was expected 28 crypto@800000: interrupt-names:4: 'eip' was expected 28 crypto@800000: interrupt-names:3: 'ring3' was expected 28 crypto@800000: interrupt-names:2: 'ring2' was expected 28 crypto@800000: interrupt-names:1: 'ring1' was expected 28 crypto@800000: interrupt-names:0: 'ring0' was expected 28 crypto@800000: 'dma-coherent' does not match any of the regexes: 'pinctrl-[0-9]+' (28 is the number of occurrences) The existing list of names defines the order AND index. Since there are 2 versions already in use, you have to define 2 lists. > > Cc: Antoine Tenart <atenart@kernel.org> > Ref: ecc5287cfe53 ("arm64: dts: mt7986: add crypto related device nodes") Not a documented tag.
