2023-03-23gpio: siox: Convert to immutable irq_chipLinus Walleij
Convert the driver to immutable irq-chip with a bit of intuition. In this case I had to figure out a way to get to the struct gpio_chip that would work even when the irq_chip is not part of the driver state container. I did this by just doing what most other GPIO drivers do and pass the state struct as data to devm_gpiochip_add_data() and rewrite accordingly.

2023-03-17drivers: remove struct module * setting from struct classGreg Kroah-Hartman
There is no need to manually set the owner of a struct class, as the registering function does it automatically, so remove all of the explicit settings from various drivers that did so as it is unneeded. This allows us to remove this pointer entirely from this structure going forward. Cc: "Rafael J.

Add minimal driver for Fairchild FXL6408 8-bit I2C-controlled GPIO expander using the generic regmap based GPIO driver (GPIO_REGMAP). The driver implements setting the GPIO direction, reading inputs and writing outputs. In addition to that the FXL6408 has the following functionalities: - allows to monitor input ports for data transitions with an interrupt pin - all inputs can be configured with pull-up or pull-down resistors Datasheet: https://www.onsemi.com/download/data-sheet/pdf/fxl6408-d.pdf Signed-off-by: Emanuele Ghidoli <emanuele.ghidoli@toradex.com> Co-developed-by: Francesco Dolcini <francesco.dolcini@toradex.com> Signed-off-by: Francesco Dolcini <francesco.dolcini@toradex.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> [Bartosz: order includes alphabetically] Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

2023-03-07ACPI: x86: Introduce an acpi_quirk_skip_gpio_event_handlers() helperHans de Goede
x86 ACPI boards which ship with only Android as their factory image usually have pretty broken ACPI tables, relying on everything being hardcoded in the factory kernel image and often disabling parts of the ACPI enumeration kernel code to avoid the broken tables causing issues. Part of this broken ACPI code is that sometimes these boards have _AEI ACPI GPIO event handlers which are broken. So far this has been dealt with in the platform/x86/x86-android-tablets.c module, which contains various workarounds for these devices, by it calling acpi_gpiochip_free_interrupts() on gpiochip-s with troublesome handlers to disable the handlers. But in some cases this is too late, if the handlers are of the edge type then gpiolib-acpi.c's code will already have run them at boot. This can cause issues such as GPIOs ending up as owned by "ACPI:OpRegion", making them unavailable for drivers which actually need them. Boards with these broken ACPI tables are already listed in drivers/acpi/x86/utils.c for e.g. acpi_quirk_skip_i2c_client_enumeration(). Extend the quirks mechanism for a new acpi_quirk_skip_gpio_event_handlers() helper, this re-uses the DMI-ids rather then having to duplicate the same DMI table in gpiolib-acpi.c . Also add the new ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS quirk to existing boards with troublesome ACPI gpio event handlers, so that the current acpi_gpiochip_free_interrupts() hack can be removed from x86-android-tablets.c .
