This seems OK.

But shouldn't PINMUX and PINMUX_${soc} also have their help text removed;
it seems like if a SoC selects PINCTRL, it would also select PINMUX if
appropriate, and the relevant PINMUX_${soc} too?
I assume there are also patches for arch/arm/mach-${foo}/Kconfig somewhere
to select PINCTRL when appropriate; they didn't show up in my inbox, but
I haven't checked my sub-folders yet, so perhaps they're already there.
