Fair enough,
Acked-by: Linus Walleij <linus.walleij at linaro.org>

However I think V.35 WAN devices (high speed serial network links)
should actually be using this? They are just some fancy serial port
after all. Cf
Documentation/devicetree/bindings/net/intel,ixp4xx-hss.yaml

No big deal I guess since they are mostly an anarchronism and not
on the table right now.
