Christian Lamparter afc056d7dc gpio-button-hotplug: support interrupt properties ... Upstream Linux's input gpio-keys driver supports specifying a external interrupt for a gpio via the 'interrupts' properties as well as having support for software debounce. This patch ports these features to OpenWrt's event version. Only the "pure" interrupt-driven support is left behind, since this goes a bit against the "gpio" in the "gpio-keys" and I don't have a real device to test this with. This patch also silences the generated warnings showing up since 4.14 due to the 'constification' of the struct gpio_keys_button *buttons variable in the upstream struct gpio_keys_platform_data declaration. gpio-button-hotplug.c: In function 'gpio_keys_get_devtree_pdata': gpio-button-hotplug.c:392:10: warning: assignment discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] button = &pdata->buttons[i++]; ^ gpio-button-hotplug.c: In function 'gpio_keys_button_probe': gpio-button-hotplug.c:537:12: warning: assignment discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] bdata->b = &pdata->buttons[i]; ^ gpio-button-hotplug.c: In function 'gpio_keys_probe': gpio-button-hotplug.c:563:37: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] struct gpio_keys_button *button = &pdata->buttons[i]; ^ Acked-by: Petr Štetiar <ynezz@true.cz> Signed-off-by: Christian Lamparter <chunkeey@gmail.com>		2019-05-31 10:30:03 +02:00
