Yes, there are already some boards (e.g. t5325 with spi0) overwriting
pinctrl settings instead of overwriting the pinctrl-0 property. I
thought, I keep this behavior and note it above each pinctrl node in
some of the following patches.
But your comment reminded me of something more important: there is
one set of boards using kirkwood-lsxl.dtsi which does not explicitly
set spi's pinctrl property. So this consolidation potentially breaks
spi on those boards.
An explicit Tested-by for Buffalo Linkstation LS-CHLv2 and/or LS-XHL
would be good.
