[PATCH 0/3] pinctrl: da9062: don't pull in internal GPIOLIB headers

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

I'm removing instances of users of internal GPIOLIB headers which should
not be included by anyone but GPIO core code. The pinctrl-da9062 driver
uses gpiochip_get_desc() which we should put into the gpio/driver.h
header as it does sometimes make sense for GPIO providers to get its own
descriptors without having to go through gpiochip_request_own_desc().

[PATCH 1/3] pinctrl: da9062: add missing include

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

gpiod_is_active_low() is defined in linux/gpio/consumer.h. It's only
because we're pulling in the gpiolib.h private header that we get this
declaration implicitly but let's fix it as that is going away soon.

For allt three patches.
Just apply them to the GPIO tree, that's easiest!

Yours,

Ok, queued, thanks!

[PATCH 2/3] gpiolib: make gpiochip_get_desc() public

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

It makes sense for a GPIO driver to want to get its own descriptor
without requesting it. After all, the driver knows that it'll still be
valid. Let's move this helper to linux/gpio/driver.h.

[PATCH 3/3] pinctrl: da9062: don't include private GPIOLIB header

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

gpiochip_get_desc() now lives in linux/gpio/driver.h and there is no
longer any need to include GPIOLIB's private header.

Linus,

Do you mind me taking these through the GPIO tree or do you prefer to
apply them yourself in which case I'll apply patch 2/3 first and
provide you with an immutable tag?
