Merge tag 'gpio-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij: "This is the big slew of GPIO changes for the v5.3 kernel cycle. This is mostly incremental work this time. Three important things: - The FMC subsystem is deleted through my tree. This happens through GPIO as its demise was discussed in relation to a patch decoupling its GPIO implementation from the standard way of handling GPIO. As it turns out, that is not the only subsystem it reimplements and the authors think it is better do scratch it and start over using the proper kernel subsystems than try to polish the rust shiny. See the commit (ACKed by the maintainers) for details. - Arnd made a small devres patch that was ACKed by Greg and goes into the device core. - SPDX header change colissions may happen, because at times I've seen that quite a lot changed during the -rc:s in regards to SPDX. (It is good stuff, tglx has me convinced, and it is worth the occasional pain.) Apart from this is is nothing controversial or problematic. Summary: Core: - When a gpio_chip request GPIOs from itself, it can now fully control the line characteristics, both machine and consumer flags. This makes a lot of sense, but took some time before I figured out that this is how it has to work. - Several smallish documentation fixes. New drivers: - The PCA953x driver now supports the TI TCA9539. - The DaVinci driver now supports the K3 AM654 SoCs. Driver improvements: - Major overhaul and hardening of the OMAP driver by Russell King. - Starting to move some drivers to the new API passing irq_chip along with the gpio_chip when adding the gpio_chip instead of adding it separately. Unrelated: - Delete the FMC subsystem" * tag 'gpio-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (87 commits) Revert "gpio: tegra: Clean-up debugfs initialisation" gpiolib: Use spinlock_t instead of struct spinlock gpio: stp-xway: allow compile-testing gpio: stp-xway: get rid of the #include <lantiq_soc.h> dependency gpio: stp-xway: improve module clock error handling gpio: stp-xway: simplify error handling in xway_stp_probe() gpiolib: Clarify use of non-sleeping functions gpiolib: Fix references to gpiod_[gs]et_*value_cansleep() variants gpiolib: Document new gpio_chip.init_valid_mask field Documentation: gpio: Fix reference to gpiod_get_array() gpio: pl061: drop duplicate printing of device name gpio: altera: Pass irqchip when adding gpiochip gpio: siox: Use devm_ managed gpiochip gpio: siox: Add struct device *dev helper variable gpio: siox: Pass irqchip when adding gpiochip drivers: gpio: amd-fch: make resource struct const devres: allow const resource arguments gpio: ath79: Pass irqchip when adding gpiochip gpio: tegra: Clean-up debugfs initialisation gpio: siox: Switch to IRQ_TYPE_NONE ...
