[GIT PULL] GPIO fixes for v4.8, take one

[Linus Walleij <linus.walleij@xxxxxxxxxx>]

Hi Linus,

here are a few GPIO fixes for v4.8. I was expecting some fallout from
the new chardev rework but nothing like that turned up att all. Instead
a Kconfig confusion that I think I have finally nailed, then some ordinary
driver noise and trivia.

Please pull these changes!

Yours,
Linus Walleij

  gpio: make any OF dependent driver depend on OF_GPIO (2016-08-19
15:01:29 +0200)

----------------------------------------------------------------
GPIO fixes for v4.8:

This fixes a Kconfig issue with UM: when I made GPIOLIB
available to all archs, that included UM, but the OF part
of GPIOLIB requires HAS_IOMEM, so we add HAS_IOMEM as a
dependency to OF_GPIO.

This in turn exposed the fact that a few GPIO drivers were
implicitly assuming OF_GPIO as their dependency but instead
depended on OF alone (the typical problem being a pointer
inside gpio_chip not existing unless OF_GPIO is selected)
and then UM would fail to compile with these drivers
instead. Then I lost patience and made any GPIO driver
depending on just OF depend on OF_GPIO instead, that is
certainly what they meant and the only thing that makes
sense anyway. GPIO with just OF but !OF_GPIO does not make
sense.

Also a fix for the max730x driver data pointer, and a minor
comment fix for the GPIO tools.
