[PATCH v5 0/2] Support Nvidia BlueField-3 GPIO driver and pin controller

[Asmaa Mnebhi <asmaa@xxxxxxxxxx>]

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 v4->v5:

gpio-mlxbf3.c:
- Update Kconfig dependency in gpio
- remove version.h header
- use irq_hw_number_t
- release lock in mlxbf3_gpio_irq_set_type
- add IRQCHIP_IMMUTABLE and GPIOCHIP_IRQ_RESOURCE_HELPERS
- remove npins property to use ngpios instead
- Assign handle_bad_irq() in probe
- Use handle_edge_irq instead  

pinctrl-mlxbf3.c:
- change the driver name to pinctrl-mlxbf3
- alignment cleanup
- use PINCTRL_PINFUNCTION
- use pinctrl_add_gpio_ranges
- use devm_platform_ioremap_resource
