Merge tag 'gpio-updates-for-v6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
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" * tag 'gpio-updates-for-v6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (30 commits) gpio: nuvoton: Fix sgpio irq handle error gpiolib: Discourage to use formatting strings in line names gpio: brcmstb: add support for gpio-ranges gpio: of: support gpio-ranges for multiple gpiochip devices dt-bindings: gpio: brcmstb: add gpio-ranges gpio: Add Intel Granite Rapids-D vGPIO driver gpio: brcmstb: Use dynamic GPIO base numbers gpiolib: acpi: Set label for IRQ only lines gpiolib: acpi: Add fwnode name to the GPIO interrupt label gpiolib: Get rid of never false gpio_is_valid() calls gpiolib: acpi: Pass con_id instead of property into acpi_dev_gpio_irq_get_by() gpiolib: acpi: Move acpi_can_fallback_to_crs() out of __acpi_find_gpio() gpiolib: acpi: Simplify error handling in __acpi_find_gpio() gpiolib: acpi: Extract __acpi_find_gpio() helper gpio: sch: Utilise temporary variable for struct device gpio: sch: Switch to memory mapped IO accessors gpio: regmap: Use -ENOTSUPP consistently gpio: pcie-idio-24: Use -ENOTSUPP consistently Documentation: gpio: Replace leading TABs by spaces in code blocks gpiolib: acpi: Check for errors first in acpi_find_gpio() ...
