8595375e4f gpio: generic: add new generic GPIO chip API 
As the first step in removing the fields specific to the gpio-mmio
module from struct gpio_chip, we introduce a new set of generic GPIO
chip interfaces that are meant to replace the existing bgpio_ ones.

The new initialization function - gpio_generic_chip_init() - takes a
configuration structure as argument instead of 9 separate parameters.
This will allow easy extension if needed in the future. We hide the
locking details behind a set of helpers in order to be able to move the
raw spinlock out of struct gpio_chip without the users noticing.

For now, the new APIs just wrap the existing ones. Once all users have
been converted to the new interfaces, we'll pull them into gpio-mmio and
implement them in a backward-compatible way while also moving all fields
specific to the generic GPIO chip into struct gpio_generic_chip.

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.

e9a5f9ac24 gpio: spear-spics: remove unneeded callbacks 
GPIO core can handle output-only chips that don't implement the get()
and direction_input() callbacks. There's no need to provide dummy
implementations in the driver so drop them.

d5297b0f86 gpio: siox: use new GPIO line value setter callbacks 
struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.

Add a reset gpio property. Note that for the adp5585-01 models, the
reset pin is used as the additional ROW5 which means there's no reset.

3bdbd0858d Input: adp5589: remove the driver 
The adp5589 support is based on legacy platform data and there's no
upstream platform using this device.
Moreover, recently, with

commit
480a8ad683 ("mfd: adp5585: Add Analog Devices ADP5585 core support")

we overlapped support for the adp5585 device (gpiochip part of it) but
since it actually makes sense for the device to be supported under MFD, we
can complement it and add the keymap support for it (properly based on FW
properties). And that is what

commit
04840c5363a6 ("Input: adp5585: Add Analog Devices ADP5585/89 support")

is doing.
