In this version, I addressed some comments from Linus Walleij. v1: https://lore.kernel.org/lkml/20190113135844.13109-1-j.neuschaefer@xxxxxxx/ This patchset implements IRQ support for the Hollywood GPIO controller (Hollywood is one of the chips in the Nintendo Wii game console). Together with two device tree patches[1], I can use the buttons (via the gpio-keys driver) and the photoelectric sensor in the disc slot (via gpio-event-mon).
