Souldn't that be <3>?
E.g. <RZ_PIN(3, 0) ALTERNATE_FUNC_6> expands to <3 0 5>, i.e. 3 numbers.
From pinctrl-bindings.txt:
#pinctrl-cells: Number of pin control cells in addition to the index
within the pin controller device instance
So here it's (2 + 1) as at least the pin index (first parameter) is
mandatory.
We're twisting the assumption of having "index" as first, single,
parameter, as we have <bank pin mode> and the <bank, pin> pair
identifies a pin.
Hope this is ok, and we can re-use existing bindings even if our
semantic is a bit different.
Gr{oetje,eeting}s,
