Merge tag 'gpio-updates-for-v7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "Nothing stands out as particularly interesting, it's been a calm
  cycle. We have three new drivers, support for more models and lots of
  updates across many modules (details are in the signed tag as usual).
  There are also some minor changes and additions to the in-kernel GPIO
  API.

  GPIO core:
   - provide a new controller API: gpiochip_generic_get_config()
   - return -EOPNOTSUPP instead of -ENODEV to user-space if it requests
     hardware timestamping on systems where it's unavailable (no
     user-space regressions reported)

  New drivers:
   - add a driver for ROHM BD73800 PMIC GPIO controller
   - add a driver for Axiado AX3005 SGPIO controller
   - add a driver for Analog Devices AD7768 GPIO controller

  New hardware support:
   - extend gpio-rcar with support for R-Car X5H (R8A78000)
   - extend gpio-tegra186 with support for Tegra 268

  Driver changes:
   - refactor and improve gpio-rtd1625: switch to modern or better
     fitting interfaces and improve coding style
   - improve error handling of return values of
     platform_get_irq_optional() in several drivers
   - normalize the return value of the gpio_chip::get() callback in
     gpio-siox in order to not propagate invalid values up to the GPIO
     core
   - implement gpio_chip::get_direction() for gpio-pcf857x
   - use managed variants of notifier registration functions in several
     drivers
   - remove legacy gpio_set_value_cansleep() as it has no more users
   - add pinctrl support to gpio-realtek-otto
   - add runtime PM support to the gpio-regmap helper module
   - add more ACPI GPIO quirks for various hardware
   - stop needlessly reading gpio_chip::base in gpio-pxa
   - add support for tracking of direction of generic GPIO chips with no
     direction registers via pinctrl backend to gpio-mmio (use the new
     core API: gpiochip_generic_get_config())
   - use the "safe" variants of debugfs_create_file() in
     gpio-sloppy-analyzer
   - use device name as GPIO chip label in gpio-omap
   - refactor bit ops in gpio-dln2
   - prepare gpio-it87 for upcoming kmalloc_obj() conversion

  Devicetree bindings:
   - document new model in gpio-pca95xx
   - allow the gpio-hogs property in gpio-zynq and fsl,qoriq-gpio
   - allow the gpio-ranges property in gpio-realtek-otto

  Misc fixes:
   - add missing MODULE_ALIAS() to gpio-crystalcove
   - fix a comment typo in example GPIO tools
   - fix unbalanced brackets in documentation
   - add names to regmaps in gpio-mvebu to avoid collisions in debugfs
     output
   - fix GPIO lookup using relative paths in GPIO ACPI"
