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"
