5a9bc389f0 driver: gpio: nct38xx: Add NCT38XX gpio driver support
NCT38XX series, which are i2c-based chips, support a different number
of GPIO functionality. For NCT3807, it has 2 GPIO ports on the same i2c
device address. For NCT3808, it has 2 GPIO ports on different i2c
device addresses. This commit adds NCT38XX GPIO driver support &
provides the interrupt handler for the share alert pin.

The following is NCT3807 devicetree node example:
```
&i2c0_0 {
	nct3807_0: nct3807@70 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "nuvoton,nct38xx-gpio";
		reg = <0x70>;
		label = "NCT3807_0";

		gpio@0 {
			compatible = "nuvoton,nct38xx-gpio-port";
			reg = <0x0>;
			label = "NCT3807_0_GPIO0";
			gpio-controller;
			#gpio-cells = <2>;
			ngpios = <8>;
			pin_mask = <0xff>;
			pinmux_mask = <0xf7>;
		};

		gpio@1 {
			compatible = "nuvoton,nct38xx-gpio-port";
			reg = <0x1>;
			label = "NCT3807_0_GPIO1";
			gpio-controller;
			#gpio-cells = <2>;
			ngpios = <8>;
			pin_mask = <0xff>;
		};
	};
};
```

b0717d518e drivers: gpio: esp32: use dts and improve code checks
This PR updates GPIO driver to use DTS information
regarding gpio availability.

This also fixes interrupt handling and
also removes kconfig definition for GPIO port.

A few configuration checks were also added to
improve code usage.

365145aa97 drivers: gpio: mmio32: Make GPIO_MMIO32_INIT dt aware
Change the GPIO_MMIO32_INIT to take a devicetree node since we want
to use DEVICE_DT_DEFINE.  This makes it so that code using
GPIO_DT_SPEC_GET works correctly with GPIO controllers that utilize
GPIO MMIO32.

cc334c7273 Convert remaining code to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.  This handles the remaining includes and kernel, plus
touching up various points that we skipped because of include
dependancies.  We also convert the PRI printf formatters in the arch
code over to normal formatters.

789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

e7391e3068 gpio: Add gpio_mmio32 driver to access basic 32-bit i/o registers
It is envisaged that this will be used by SoC or board code to make
available fixed purpose memory-mapped i/o registers to the rest of the
system which normally expects to use GPIO devices, e.g. for driving chip
select lines, LEDs or reading button states.

As such, the driver code doesn't provide a kconfig based configuration
mechanism, instead SoC/board code can hard-wire the devices it wants
with something simple like:

GPIO_MMIO32_INIT(misc_reg1, "MISC1", 0x12345678, 0xffffffffu)

Then, for example, if bit N of the register at 0x12345678 is wired up as
an SPI device chip select line, the SPI driver could be configured to
use pin N of the "MISC1" GPIO driver and not need any other board
specific code.
