Is there any scenario where these drivers should be user selected?  My
feel is that the right thing to do with gpio controllers is to just
build them in when the platform is selected.  We can always add
Kconfig entries later if this assumption changes.

My preference is to just drop the filename from the header entirely.
A better thing here would be a single line description of what this
file actually does.

drivers/gpio/gpio-*.c please.  I'm starting to enforce some level of
naming convention.

Hrm, looking at the current mainline drivers the existing tendency seems
to be mostly towards gpio/*-gpio.c...

However, drivers/i2c/busses is nicely organized with i2c-*.c, and a
lot of the spi drivers are drivers/spi/spi* (although it is a mixed
bag here).  I also personally prefer the drivers to have the type as
a prefix instead of a suffix, and I hope to reorganize both
drivers/spi and drivers/gpio to follow the i2c lead in the next
cycle.

True, this does come down to personal taste, but unless someone has a
really strong objection to it then I'll keep asking for new drivers to
use gpio- as a prefix.

Right, my thought was more that if that's going to be the way forward
it's probably worth renaming the existing drivers so people don't get
confused - people are likely to pick the visible convention as their
first thought so we should either standardise on the existing one or
change what's there.  It's nicer if what you're supposed to do is what
everyone's actually doing :)
