Sylvio Alves 82bd341018 drivers: gpio: esp32: fix error when using input only pins
Input pins in ESP32 (34 to 39) have no pull-up / pull-down internally.
Current behavior is that gpio driver fails when "disabling it", which
should not happen. It need to fail only when enabling this feature.

Fixes #50615

Sylvio Alves 3c50237460 drivers: gpio: esp32: fix config function to allow changes
Current implementation misses disabling input/output mux
once GPIO has already been configured. It means that after 1st
configuration, if GPIO is reconfigured, it won't disable previous
definitions, causing unexpected behavior.

Stephanos Ioannidis 11d27f12ad drivers: gpio_esp32: Drop IRAM_ATTR from forward declarations
This commit drops the `IRAM_ATTR` macro from the function declarations
because:

1. `IRAM_ATTR` macro makes use of the `__COUNTER__` preprocessor macro,
   which increments for every macro invocation and causes the section
   specified in the forward declaration to not match that of the
   function definition.

2. Section attributes need not be specified for forward declarations.

Henrik Brix Andersen d4023b3c1b drivers: gpio: move non-standard dts flags to be soc specific
Reserve the upper 8 bits of gpio_dt_flags_t for SoC specific flags and
move the non-standard, hardware-specific GPIO devicetree flags (IO
voltage level, drive strength, debounce filter) from the generic
dt-bindings/gpio/gpio.h header to SoC specific dt-bindings headers.

Some of the SoC specific dt-bindings flags take up more bits than
necessary in order to retain backwards compatibility with the deprecated
GPIO flags. The width of these fields can be reduced/optimized once the
deprecated flags are removed.

Remove hardcoded use of GPIO_INT_DEBOUNCE in GPIO client drivers. This
flag can now be set in the devicetree for boards/SoCs with debounce
filter support. The SoC specific debounce flags have had the _INT part
of their name removed since these flag must be passed to
gpio_pin_configure(), not gpio_pin_interrupt_configure().

As a complement of 7689abee34,
which fixed an issue where gpio number could errouneously be

Maureen Helm 836651b453 drivers: gpio: Refactor drivers to use shared init priority
Refactors all of the on-chip GPIO drivers to use a shared driver class
initialization priority configuration, CONFIG_GPIO_INIT_PRIORITY, to
allow configuring GPIO drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.

Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_DEFAULT or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.

Driver-specific options for off-chip I2C- or SPI-based GPIO drivers are
left intact because they often need to be initialized at a different
priority than on-chip GPIO drivers.
