Merge tag 'gpio-updates-for-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
"One new driver, support for new models in existing ones, dt-bindings
conversions for several modules and improvements all over the place.

Summary:

- new driver for the IDT 79RC3243x GPIO controller

- device tree bindings coversion to YAML for the following drivers:
gpio-rk3328-grf, gpio-omap, gpio-davinci, gpio-zynq, gpio-stp,
gpio-pcf857x

- cleanup of probe functions in many drivers from Alexandru Ardelean,
mostly dropping unnecessary calls to platform_set_drvdata() and
removing error messages where none are needed (handled by the
subsystem already)

- several improvements to the core gpiolib and the sysfs interface
code from Andy Shevchenko

- conversion of the gpio-xilinx driver to using the bitmap API +
improvements of suspend/resume handling + minor tweaks

- convert the gpio-stmpe to using devres helpers exclusively in probe
for improved robustness

- updates for the generic gpio-regmap driver

- updates for the gpio-dwapb driver

- support for a new model in gpio-pca953x

- cleanups in gpio-tegra186, gpio-104-idio-16, gpio-mxs & gpio-xgene

- slight code refactoring of the gpio-zynq driver

- documentation fixes from Mauro Carvalho Chehab

- a bunch of minor tweaks and improvements all over the place"

gpio: idt3243x: Fix return value check in idt_gpio_probe()

In case of error, the function devm_platform_ioremap_resource_byname()
returns ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().

gpio: Add support for IDT 79RC3243x GPIO controller

IDT 79RC3243x SoCs integrated a gpio controller, which handles up
to 32 gpios. All gpios could be used as an interrupt source.
