The gpiolib is moving to make irq_chip immutable, otherwise there is warning: "not an immutable chip, please consider fixing it!"

2025-05-15gpio: TODO: add item about GPIO drivers reading struct gpio_chip::baseAhmad Fatoum
drivers/pinctrl/pinctrl-at91.c uses struct gpio_chip::base to find out which bit to set in a register: dev_dbg(npct->dev, "enable pin %u as GPIO\n", offset); mask = 1 << (offset - chip->base); This adds a non-obvious dependency on the global numberspace from the GPIO driver itself, even if all consumers use the descriptor API. More such instances may exist and will need to be fixed in the quest for removal of the global numberspace, so add a reminder about it to the TODO list.

2025-05-15gpio: mxc: configure dynamic GPIO base for CONFIG_GPIO_SYSFS=nAhmad Fatoum
i.MX GPIO numbering has been deterministic since commit 7e6086d9e54a ("gpio/mxc: specify gpio base for device tree probe"), a year after device tree support was first added back in 2011. Reverting to dynamically allocated GPIO base now would break most systems making use of the sysfs API. These systems will be eventually broken by the removal of the sysfs API, but that would result in GPIO scripts not working instead of essentially toggling at random according to probe order, which would happen if we unconditionally set base to -1. Yet, the warning is annoying and has resulted in many rejected attempts to remove it over the years[1][2][3]. As the i.MX GPIO driver is device tree only, GPIO_SYSFS is the only consumer of the deterministic GPIO numbering. Let's therefore restrict the static base and the warning that comes with it to configurations with CONFIG_GPIO_SYSFS enabled.

2025-04-28devres: Move devm_*_action*() APIs to devres.hAndy Shevchenko
We have a newly created header linux/device/devres.h that gathers device managed APIs, so users won't need to include entire device.h for only these ones. Move devm_*_action*() APIs to devres.h as well.
