gpio: Remove unused and obsoleted irq_to_gpio()

2023-01-30T14:55:29Z

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.

Documentation: gpio: Remove text about ARCH_NR_GPIOS

2022-10-17T09:03:20Z

ARCH_NR_GPIOS have been removed, clean up the documentation. After this patch, the only place when ARCH_NR_GPIOS remains is in translations/zh_CN/gpio.txt and translations/zh_TW/gpio.txt. I don't have the skills to update that, anyway those two files are already out of sync as they are still mentionning ARCH_REQUIRE_GPIOLIB which was removed by commit 65053e1a7743 ("gpio: delete ARCH_[WANTS_OPTIONAL|REQUIRE]_GPIOLIB") Signed-off-by: Christophe Leroy Reviewed-by: Andy Shevchenko Signed-off-by: Bartosz Golaszewski

Documentation: gpio: Advertise irqd_to_hwirq() helper in the examples

2022-05-16T17:16:54Z

Instead of direct dereferencing the IRQ data in order to get HW IRQ number use the irqd_to_hwirq() helper. Fixes: 5644b66a9c63 ("Documentation: Update the recommended pattern for GPIO irqchips") Signed-off-by: Andy Shevchenko Reviewed-by: Linus Walleij

Documentation: gpio: Fix IRQ mask and unmask examples

2022-05-16T17:16:54Z

After switching to immutable IRQ chips for GPIO drivers the examples become uncompilable due to wrong IRQ API, i.e. irq_desc_get_handler_data() in use. Replace it with proper irq_data_get_irq_chip_data() call where it applies.
