-Subject: [PATCH 088/110] bcma: gpio: add own IRQ domain
-
-Input GPIO changes can generate interrupts, but we need kind of ACK for
-them by changing IRQ polarity. This is required to stop hardware from
-keep generating interrupts and generate another one on the next GPIO
-state change.
-This code allows using GPIOs with standard interrupts and add for
-example GPIO buttons support.
