Merge tag 'gpio-updates-for-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "Relatively few updates for this release cycle. We have a single new
  driver and some minor changes in drivers, more work on limiting the
  usage of of_node in drivers and DT updates:

   - new driver: gpio-en7523

   - dt-bindings: convertion of faraday,ftgpio010 to YAML, new
     compatible string in gpio-vf610 and a bugfix in an example

   - gpiolib core: several improvements and some code shrink

   - documentation: convert all public docs into kerneldoc format

   - set IRQ bus token in gpio-crystalcove (addresses a debugfs issue)

   - add a missing return value check for kstrdup() in gpio-merrifield

   - allow gpio-tps68470 to be built as module

   - more work on limiting usage of of_node in GPIO drivers

   - several sysfs interface improvements

   - use SDPX in gpio-ts4900"
