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" * tag 'gpio-updates-for-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: gpio: ts4900: Use SPDX header gpiolib: Use list_first_entry()/list_last_entry() gpiolib: sysfs: Simplify edge handling in the code gpiolib: sysfs: Move kstrtox() calls outside of the mutex lock gpiolib: sysfs: Move sysfs_emit() calls outside of the mutex lock gpiolib: make struct comments into real kernel docs dt-bindings: gpio: convert faraday,ftgpio01 to yaml dt-bindings: gpio: gpio-vf610: Add imx93 compatible string gpiolib: Simplify error path in gpiod_get_index() when requesting GPIO gpiolib: Use short form of ternary operator in gpiod_get_index() gpiolib: Introduce for_each_gpio_desc_with_flag() macro gpio: Add support for Airoha EN7523 GPIO controller dt-bindings: arm: airoha: Add binding for Airoha GPIO controller dt-bindings: gpio: fix gpio-hog example gpio: tps68470: Allow building as module gpio: tegra: Get rid of duplicate of_node assignment gpio: altera-a10sr: Switch to use fwnode instead of of_node gpio: merrifield: check the return value of devm_kstrdup() gpio: crystalcove: Set IRQ domain bus token to DOMAIN_BUS_WIRED
