Merge tag 'gpio-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.6 kernel cycle. This is a pretty calm cycle so far, nothing special going on really. Some more changes will come in from the irqchip and pin control trees. I also deleted an orphan include file for FMC that was dangling since subsystem was removed. Core changes: - Document the usecases for the kernelspace vs userspace handling of GPIOs. - Handle MSI (message signalled interrupts) properly in the core hierarchical irqdomain code. - Fix a rare race condition while initializing the descriptor array. New drivers: - Xylon LogiCVC GPIO driver. - WDC934x GPIO controller driver. Driver improvements: - Implemented suspend/resume in the Tegra driver. - MPC8xx edge detection fixup. - Properly convert ThunderX to use hierarchical irqdomain with GPIOLIB_IRQCHIP on top of the revert of the previous buggy switchover. This time it works (hopefully). Misc: - Drop a FMC remnant file <linux/ipmi-fru.h> - A slew of fixes" * tag 'gpio-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (48 commits) MAINTAINERS: Replace Tien Hock Loh as Altera PIO maintainer gpiolib: hold gpio devices lock until ->descs array is initialised gpio: aspeed-sgpio: fixed typos gpio: mvebu: clear irq in edge cause register before unmask edge irq gpiolib: Lower verbosity when allocating hierarchy irq gpiolib: Remove duplicated function gpio_do_set_config() gpio: Fix the no return statement warning gpio: wcd934x: Add support to wcd934x gpio controller gpiolib: remove set but not used variable 'config' gpio: vx855: fixed a typo gpio: mockup: sort headers alphabetically gpio: mockup: update the license tag gpio: Remove the unused flags gpiolib: Set lockdep class for hierarchical irq domains gpio: thunderx: Switch to GPIOLIB_IRQCHIP gpiolib: Add the support for the msi parent domain gpiolib: Add support for the irqdomain which doesn't use irq_fwspec as arg gpio: Add use guidance documentation dt-bindings: gpio: wcd934x: Add bindings for gpio gpio: altera: change to platform_get_irq_optional to avoid false-positive error ...
