Support the BlueField-3 SoC GPIO driver for handling interrupts and providing the option to change the direction and value of a GPIO. Support the BlueField-3 SoC pin controller driver for allowing a select number of GPIO pins to be manipulated from userspace or the kernel. The gpio-mlxbf3.c driver handles hardware registers and logic that are different from gpio-mlxbf.c and gpio-mlxbf2.c. For that reason, we have separate drivers for each generation. Changes from v3->v4: gpio-mlxbf3.c: - Update the Kconfig file so that it is conform with checkpatch - Remove unncessary headers and add missing header inclusions - Make irq_chip struct static and const - Replace generic_handle_irq(irq_find_mapping) with generic_handle_domain_irq - Simplify logic in irq_set_type - Replace valid_mask with gpio-reserved-ranges - Cleanup code pinctrl-mlxbf.c: - Cleanup code - Update the Kconfig file so that it is conform with checkpatch - Remove unncessary headers and add missing header inclusions Asmaa Mnebhi (2): gpio: gpio-mlxbf3: Add gpio driver support pinctrl: pinctrl-mlxbf: Add pinctrl driver support drivers/gpio/Kconfig | 12 ++ drivers/gpio/Makefile | 1 + drivers/gpio/gpio-mlxbf3.c | 230 ++++++++++++++++++++++ drivers/pinctrl/Kconfig | 14 ++ drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-mlxbf.c | 338 ++++++++++++++++++++++++++++++++ 6 files changed, 596 insertions(+) create mode 100644 drivers/gpio/gpio-mlxbf3.c create mode 100644 drivers/pinctrl/pinctrl-mlxbf.c -- 2.30.1
