It was rumored that Arnd wanted to take over drivers/char/.

That's true. It probably means I should set up a tree now, before we get
too close to the next merge window.
On the topic of drivers/char/{nsc_gpio,pc8736x_gpio,scx200_gpio}, I wonder
if we should move them to drivers/gpio/nsc_gpio despite the fact that they
use a different (older) interface than all the other gpio drivers.
They have seen only a single non-janitor patch in the last five years,
so I don't think they will be a burden, but it might be nice to have them
in a place where people would actually look for them, with a comment that
they should be converted to the new API in order to be more useful.

I have no problem with moving them into drivers/gpio. When you do,
please rename then drivers/gpio/gpio-*.c

Ok. Should they be in a subdirectory drivers/gpio/nsc_gpio/gpio_* for the
nonstandard API or do you prefer them to live amongst the regular ones?

converting these to gpiolib has been on my list for a while, but
pretty far down.
Moving them is an easy 1st step.
Once theyre converted, I guess they belong with the others,
but its easy to move them again when the convert is done.
preference ?

I only see one files per non-standard driver. I wouldn't bother with
subdirectories. Just put them in with the general population.
