There are only few devices using it: it is declared in
kirkwood-6192.dtsi and that is just used by:

kirkwood-blackarmor-nas220.dts
kirkwood-laplug.dts
kirkwood-rd88f6192.dts
... and my new device tree

Interestingly, kirkwood-ns2[lite|mini].dts specifies it's compatible
with "marvell,kirkwood-88f6192" but instead includes
kirkwood-ns2-common.dtsi which includes
kirkwood-6281.dtsi. I haven't wrapped my head around that
one, I suspect it's a bug.

Yours,
