This series of patches creates a pin controller driver and GPIO driver for NVIDIA BlueField-3 SoC. The first patch creates a GPIO driver for handling interrupts and allowing the change of direction and value of a GPIO if needed. The second patch creates a pin controller driver for allowing a select number of GPIO pins to be manipulated from userspace or the kernel. The BlueField-3 SoC gpio-mlxbf3.c driver handles different hardware registers and logic that from gpio-mlxbf.c and gpio-mlxbf2.c. For that reason, we have separate drivers for each generation. Changes from v2->v3: Addressed the following comments from maintainers: - bgpio_init can handle direction_input and direction_output - Update pinctrl Kconfig to select GPIO_MLXBF3 - remove unnecessary #includes from gpio-mlxbf3.c and pinctrl-mlxbf.c Asmaa Mnebhi (2): Support NVIDIA BlueField-3 GPIO controller Support NVIDIA BlueField-3 pinctrl driver drivers/gpio/Kconfig | 7 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-mlxbf3.c | 262 ++++++++++++++++++++++++ drivers/pinctrl/Kconfig | 10 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-mlxbf.c | 341 ++++++++++++++++++++++++++++++++ 6 files changed, 622 insertions(+) create mode 100644 drivers/gpio/gpio-mlxbf3.c create mode 100644 drivers/pinctrl/pinctrl-mlxbf.c -- 2.30.1
