Pull gpio updates from Bartosz Golaszewski
 "This was a quiet release cycle for the GPIO tree and so this
  pull-request is relatively small.

  We have one new driver, some minor improvements to the GPIO core code
  and across several drivers, some DT and documentation updates but in
  general nothing stands out or is controversial. All changes have spent
  time in next with no reported issues (or ones that were quickly
  fixed).

  GPIO core:
   - remove more unused legacy interfaces (after converting the last
     remaining users to better alternatives)
   - update kerneldocs
   - improve error handling and log messages in GPIO ACPI code
   - remove dead code (always true checks) from GPIOLIB

  New drivers:
   - add a driver for Intel Granite Rapids-D vGPIO

  Driver improvements:
   - use -ENOTSUPP consistently in gpio-regmap and gpio-pcie-idio-24
   - provide an ID table for gpio-cros-ec to avoid a driver name
     fallback check
   - add support for gpio-ranges for GPIO drivers supporting multiple
     GPIO banks
   - switch to using dynamic GPIO base in gpio-brcmstb
   - fix irq handling in gpio-npcm-sgpio
   - switch to memory mapped IO accessors in gpio-sch

  DT bindings:
   - add support for gpio-ranges to gpio-brcmstb
   - add support for a new model and the gpio-line-names property to
     gpio-mpfs

  Documentation:
   - replace leading tabs with spaces in code blocks
   - fix typos"
