GPIO core can handle output-only chips that don't implement the get()
and direction_input() callbacks. There's no need to provide dummy
implementation of the latter in the driver so drop it.

c4a8348405 gpio: mmio: get chip label and GPIO base from device properties 
Ahead of removing struct bgpio_pdata support from the gpio-mmio generic
module, let's add support for getting the relevant values from generic
device properties. "label" is a semi-standardized property in some GPIO
drivers so let's go with it. There's no standard "base" property, so
let's use the name "gpio-mmio,base" to tie it to this driver
specifically. The number of GPIOs will be retrieved using
gpiochip_get_ngpios() so there's no need to look it up in the software
node.

30e0fd3c02 gpiolib: fix performance regression when using gpio_chip_get_multiple() 
commit 74abd086d2 ("gpiolib: sanitize the return value of
gpio_chip::get_multiple()") altered the value returned by
gc->get_multiple() in case it is positive (> 0), but failed to return
for other cases (<= 0).

This may result in the "if (gc->get)" block being executed and thus
negates the performance gain that is normally obtained by using
gc->get_multiple().

Fix by returning the result of gc->get_multiple() if it is <= 0.

Also move the "ret" variable to the scope where it is used, which as an
added bonus fixes an indentation error introduced by the aforementioned
commit.

988b28a83b gpio: adp5585: support gpi events 
Add support for adding GPIs to the event FIFO. This is done by adding
irq_chip support. Like this, one can use the input gpio_keys driver as a
"frontend" device and input handler.

As part of this change, we now implement .request() and .free() as we can't
blindly consume all available pins as GPIOs (example: some pins can be
used for forming a keymap matrix).

Also note that the number of pins can now be obtained from the parent,
top level device. Hence the 'max_gpio' variable can be removed.

3315e39e56 gpio: rcar: Use new line value setter callbacks 
struct gpio_chip now has callbacks for setting line values that return
integers, so they can indicate failures.  Convert the driver to using
them.

28a9ab01f6 gpio: rcar: Remove checks for empty bankmasks 
The GPIO core never passes empty bankmasks to the callbacks for handling
multiple signals at once.  Remove the superfluous checks, and refactor
the code.

23b33cf124 gpio: clps711x: drop unneeded platform_set_drvdata() 
There's no corresponding platform_get_drvdata() used in this module or
the higher-level gpio-mmio. Let's remove the unneeded call to
platform_set_drvdata().
