Pull gpio updates from Bartosz Golaszewski:
"There are two new drivers and support for more models in existing
ones.
The generic GPIO API has been reworked and all users converted
which allowed us to move the fields specific to the generic GPIO
implementation out of the high-level struct gpio_chip into its own
structure that wraps the gpio_chip.
Other than that, there's nothing too exciting. Mostly minor tweaks and
fixes all over the place, some refactoring and some small new features
in helper modules.
GPIO core:
- add support for sparse pin ranges to the glue between GPIO and
pinctrl
- use a common prefix across all GPIO descriptor flags for improved
namespacing
New drivers:
- add new GPIO driver for the Nuvoton NCT6694
- add new GPIO driver for MAX7360
Driver improvements:
- add support for Tegra 256 to the gpio-tegra186 driver
- add support for Loongson-2K0300 to the gpio-loongson-64bit driver
- refactor the gpio-aggregator module to expose its GPIO forwarder
API to other in-kernel users (to enable merging of a new pinctrl
driver that uses it)
- convert all remaining drivers to using the modernized generic GPIO
chip API and remove the old interface
- stop displaying global GPIO numbers in debugfs output of controller
drivers
- extend the gpio-regmap helper with a new config option and improve
its support for GPIO interrupts
- remove redundant fast_io parameter from regmap configs in GPIO
drivers that already use MMIO regmaps which imply it
- add support for a new model in gpio-mmio: ixp4xx expansion bus
- order includes alphabetically in a few drivers for better
readability
- use generic device properties where applicable
- use devm_mutex_init() where applicable
- extend build coverage of drivers by enabling more to be compiled
with COMPILE_TEST enabled
- allow building gpio-stmpe as a module
- use dev_err_probe() where it makes sense in drivers
Late driver fixes:
- fix setting GPIO direction to output in gpio-mpfs
Documentation:
- document the usage of software nodes with GPIO chips
Device-tree bindings:
- Add DT bindings documents for new hardware: Tegra256, MAX7360
- Document a new model in Loongson bindings: LS2K0300
- Document a new model using the generic GPIO binding: IXP4xx
- Convert the DT binding for fsl,mxs-pinctrl to YAML
- fix the schema ID in the "trivial" GPIO schema
- describe GPIO hogs in the generic GPIO binding"

Add str_assert_deassert() helper to return "assert" or "deassert"
string literal depending on the boolean argument. Also add the
inversed variant str_deassert_assert().

Similar to the exists helper: str_enable_disable/
str_enabled_disabled/str_on_off/str_yes_no helpers, we can
add the opposite helpers. That's str_disable_enable,
str_disabled_enabled, str_off_on and str_no_yes.
There are more than 10 cases currently (expect
str_disable_enable now has 3 use cases) exist in the code
can be replaced with these helper.

The string choice functions which are not clearly true/false synonyms
also have inverted wrappers. Add this for str_down_up() as well.

Some users may only need the string choice APIs. Split
the respective header, i.e. string_choices.h. Include
it in the string_helpers.h for backward compatibility.
