gpio: Remove unused and obsoleted irq_to_gpio()

2023-01-30T14:55:29+00:00

irq_to_gpio() is legacy and unused API, remove it for good.

This leaves gpio_to_irq() as it's used yet in many places.
Nevertheless, removal of its counterpart is a good signal
to whoever even trying to consider using them that do not.

gpiolib: Clean up headers

2022-10-24T09:30:26+00:00

There is a few things done:
- include only the headers we are direct user of
- when pointer is in use, provide a forward declaration
- add missing headers
- group generic headers and subsystem headers
- sort each group alphabetically

While at it, fix some awkward indentations.

gpiolib: devres: Get rid of unused devm_gpio_free()

2022-07-19T07:56:34+00:00

The last user, which in fact was a dead code, has gone a year ago,
previous one 3 years ago. On top of that we want to drop away the
legacy GPIO APIs in the kernel, so take a chance to get rid of
unused devm_gpio_free() and accompanying stuff.

gpio: Avoid kernel.h inclusion where it's possible

2020-02-10T11:58:36+00:00

Inclusion of kernel.h increases the mess with the header dependencies.
Avoid kernel.h inclusion where it's possible.

Besides that, clean up a bit other inclusions inside GPIO subsystem headers.
It includes:
 - removal pin control bits (forward declaration and header) from linux/gpio.h
 - removal of.h from asm-generic/gpio.h
 - use of explicit headers in gpio/consumer.h
 - add FIXME note with regard to gpio.h inclusion in of_gpio,h

If CONFIG_GPIOLIB is not, gpiochip_lock/unlock_as_irq will

Move them to gpio/driver.h and use CONFIG_GPIOLIB guard this.
