Which spec has all these?
Now, I'm also not at all sure we should "whitelist" tons of gpio
references here, especially since most of them are not at all about
display. It's really scary to think of our driver messing with, say,
emmc or camera gpio pins on modeset.

The thing you pass to gpio_set_value is the gpio number. What you call
"function" and "offset" here are (if what you're doing is correct)
simply the gpio number. That's what you should call it.
What you call "gpio" and "gpio_pin" here, then actually isn't the gpio
number, but something else. You should call it something else.

If you can't request it, you shouldn't free it.

You might just as well rename action to value, to be in line with
gpiolib parlance.

Yes, I said that you need to free the gpio, but I also tried to say that
you are *not* supposed to request/free the gpio every time you need to
set its value. Have a look at what gpio request and free actually
involve. Requesting an output gpio forces the value according to flags,
and you may inadvertently toggle the gpio back and forth more than you
think.
You might get away with lazily requesting the gpio on first use (but
also then setting the initial value according to "action"), and then
freeing them all at driver unload.

Also, at least for now, please also post all the patches as a new
thread. The way you're replying to the thread with new patch revisions
will confuse patchwork.
