Merge tag 'gpio-updates-for-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into devel
gpio updates for v5.11-rc1 - several refactoring patches of the core gpiolib code - add support for NXP PCAL9554B/C to gpio-pca953x - allow probing mockup devices from device tree - refactoring and improvements to gpio-rcar - improvements to locking in gpio-tegra - code shrink in gpiolib devres - get the irq offset from device tree in gpio-sifive - major refactoring of gpio-exar - convert gpio-mvebu pwm access to regmap - create a new submenu for virtual GPIO drivers - fix clang fall-through warnings treewide - minor driver refactoring and tweaks sprinkled all over
