2025-09-12gpio: move gpio-mmio-specific fields out of struct gpio_chipBartosz Golaszewski6-233/+211
With all users of bgpio_init() converted to using the modernized generic GPIO chip API, we can now move the gpio-mmio-specific fields out of struct gpio_chip and into the dedicated struct gpio_generic_chip. To that end: adjust the gpio-mmio driver to the new layout, update the docs, etc. The changes in gpio-mlxbf2.c and gpio-mpc8xxx.c are here and not in their respective conversion commits because the former passes the address of the generic chip's lock to the __releases() annotation and we cannot really hide it while gpio-mpc8xxx.c accesses the shadow registers in a driver-specific workaround and there's no reason to make them available in a public API. Also: drop the relevant task from TODO as it's now done.

Use devm_mutex_init() instead of hand-writing it. This saves some LoC, improves readability and saves some space in the generated .o file.

2025-09-08gpio: loongson-64bit: Add support for Loongson-2K0300 SoCYao Zi2-7/+183
This controller's input and output logic is similar to previous generations of SoCs. Additionally, it's capable of interrupt masking, and could be configured to detect levels and edges, and is supplied with a distinct reset signal. The interrupt functionality is implemented through an irqchip, whose operations are written with previous generation SoCs in mind and could be reused. Since all Loongson SoCs with similar interrupt capability (LS2K1500, LS2K2000) support byte-control mode, these operations are for byte-control mode only for simplicity.

2025-09-08dt-bindings: gpio: loongson: Document GPIO controller of LS2K0300 SoCYao Zi1-1/+27
Loongson-2K0300 ships a GPIO controller whose input/output control logic is similar to previous generation of SoCs. Additionally, it acts as an interrupt-controller supporting both level and edge interrupts and has a distinct reset signal. Describe its compatible in devicetree. We enlarge the maximum value of ngpios to 128, since the controller technically supports at most 128 pins, although only 106 are routed out of the package. Properties for interrupt-controllers and resets are introduced and limited as LS2K0300 only.
