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 2022-03-10gpio: ts4900: Use SPDX headerKris Bahnsen Remove boilerplate, use the SPDX license identifier.

If both are updated simultaneously, the harware makes no guarantees that OE or DAT will actually change in any given order and may result in a glitch of a few ns on a GPIO pin when changing direction and value in a single write. Setting direction to input now only affects OE bit. Setting direction to output updates DAT first, then OE.
