From 2997609eb4c9e296d9129d45ea1f2ec99cc7c4da Mon Sep 17 00:00:00 2001 From: Rafał Miłecki Date: Thu, 12 Dec 2013 13:46:03 +0100 Subject: bcma: gpio: add own IRQ domain MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
