This file is currently getting module.h from a global gpio header
and it will faii to build once we remove module.h from that.However, the driver is controlled with the following Kconfig:
drivers/gpio/Kconfig:config GPIO_SX150X
drivers/gpio/Kconfig: bool "Semtech SX150x I2C GPIO expander"and hence the two lines of MODULE_DEVICE_TABLE are no-ops that
can simply be deleted.Cc: Linus Walleij

drivers/gpio/Kconfig:config GPIO_PALMAS
drivers/gpio/Kconfig: bool "TI PALMAS series PMICs GPIO"and hence the line of MODULE_DEVICE_TABLE is a no-op that can simply
be deleted. In fact it should have been removed in an earlier commit
that did demodularization, however the unseen include prevented my
build testing from detecting it.Cc: Linus Walleij

This reverts commit 313b9a9938bf4076425741121d5d766826793e5d.
This was already fixed by
commit bf62efeb164343916ebb89dca6dfe5e6b6751700
"gpio: pca954x: fix undefined error code from remove"The latter is a better fix since it makes it easier to detect
erronous code by not assigning a default error code.Reported-by: Arnd Bergmann

There are multiple places in the driver code where a
switch (chip->chip_type) is used to determine the proper register
offset.Unduplicate the code by adding a simple structure holding the possible
offsets that differ between the pca953x and pca957x chip families and
use it to avoid the checks.Signed-off-by: Bartosz Golaszewski

Using a default trigger is a bad idea if using DT to configure
interrupts, as the device's interrupt specifier will always contain
the trigger configuration.Let's warn about that particular situation, and revert to not
having a default. Hopefully, the couple of drivers still using
this feature will quickly be fixed.Signed-off-by: Marc Zyngier

The Aspeed SoCs contain GPIOs banked by letter, where each bank contains
8 pins. The GPIO banks are then grouped in sets of four in the register
layout.The implementation exposes multiple banks through the one driver and
requests and releases pins via the pinctrl subsystem. The hardware
supports generation of interrupts from all GPIO-capable pins.A number of hardware features are not yet supported: Configuration of
interrupt direction (ARM or LPC), debouncing, and WDT reset tolerance
for output ports.Signed-off-by: Joel Stanley

The recent addition of the regulator support has led to the pca953x_remove
function returning uninitialized data when no platform data pointer is
provided, as gcc warns when using -Wmaybe-uninitialized:drivers/gpio/gpio-pca953x.c: In function 'pca953x_remove':

The Kconfig currently controlling compilation of this code is:
drivers/gpio/Kconfig:config GPIO_VF610
drivers/gpio/Kconfig: def_bool y...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.We delete the MODULE_LICENSE tag etc. since all that information
is now contained at the top of the file in the comments.We don't replace module.h with init.h since the file already has that.
