gpiolib: remove unused gpio_cansleep()

2023-06-13T14:49:23+00:00

There is not a single user in the entire kernel of this deprecated API, kill it for good. Signed-off-by: Andy Shevchenko Reviewed-by: Yanteng Si Reviewed-by: Linus Walleij Signed-off-by: Bartosz Golaszewski

gpiolib: Clean up headers

2023-03-06T10:33:02+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 Signed-off-by: Andy Shevchenko

gpiolib: remove legacy gpio_export()

2023-03-06T10:33:01+00:00

There are only a handful of users of gpio_export() and related functions. As these are just wrappers around the modern gpiod_export() helper, remove the wrappers and open-code the gpio_to_desc in all callers to shrink the legacy API.

gpiolib: remove gpio_set_debounce()

gpio_set_debounce() only has a single user, which is trivially converted to gpiod_set_debounce(). Signed-off-by: Arnd Bergmann Reviewed-by: Linus Walleij Reviewed-by: Andy Shevchenko Signed-off-by: Andy Shevchenko

gpiolib: remove asm-generic/gpio.h

2023-03-06T10:33:01+00:00

The asm-generic/gpio.h file is now always included when using gpiolib, so just move its contents into linux/gpio.h with a few minor simplifications. Signed-off-by: Arnd Bergmann Reviewed-by: Linus Walleij Reviewed-by: Andy Shevchenko Signed-off-by: Andy Shevchenko

gpiolib: coldfire: remove custom asm/gpio.h

2023-03-06T10:33:01+00:00

Now that coldfire is the only user of a custom asm/gpio.h, it seems better to remove this as well, and have the same interface everywhere. For the gpio_get_value()/gpio_set_value()/gpio_to_irq(), gpio_cansleep() functions, the custom version is only a micro-optimization to inline the function for constant GPIO numbers. However, in the coldfire defconfigs, I was unable to find a single instance where this micro-optimization was even used, and according to Geert the only user appears to be the QSPI chip that is disabled everywhere. The custom gpio_request_one() function is even less useful, as it is guarded by an #ifdef that is never true.

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.
