I think the TODO list is in Linus' head,

Oh no, drivers/gpio/TODO

but it would include all the files
that use one of the interfaces in linux/gpio.h. I found about 350 of them,
so there is little point in listing them one at a time. IIRC Linus is going
through those one subsystem at a time.

Yeah but if it's just me I doubt that I will manage to do it by the
time I retire in 2037 or so... So the TODO is there to inspire others
to step in and help out.

I also found that we have a ton of users of linux/of_gpio.h, which is
somewhere inbetween the linux/gpio.h interface and the
linux/gpio/consumer.h version.

This is also mentioned in the TODO.
