Gerard Marull-Paretas fb60aab245 drivers: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

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().

Andrzej Głąbek 89cc06e588 drivers: gpio_pcal6408a: Fix handling of the GPIO_INT_DEBOUNCE flag
Ignore the flag instead of rejecting it with -ENOTSUP, as this is what
the GPIO API expects from drivers that do not support debouncing.

Henrik Brix Andersen 2e8cc9f9b0 drivers: gpio: add combined drive strength flags and mask
Introduce combined GPIO drive strength flags for GPIO controllers only
supporting either default or alternative drive strength regardless if
the pin is driven to a high or a low level.
