Merge tag 'gpio-v5.2-updates-for-linus-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into devel
gpio: updates for v5.2 (part 1) - batch of improvements for the vf610 driver which shrink the code and make use of resource managed helpers - support for a new variant of pca953x - make gpio-mockup buildable on systems without IOMEM - make gpio-74x164 more flexible by using generic device properties plus minor improvements - new driver for Mellanox BlueField - fixes for wakeup GPIOs in gpio-omap - use devm_platform_ioremap_resource() in gpio-mxc - a couple improvements of kernel docs for ACPI code - don't WARN() in gpiod_put() on optional GPIOs
