From: Hans de Goede <hdegoede@xxxxxxxxxx> It has taken me a long long time to get the OOB interrupt working on the AP6210 sdio wifi/bt module found on various Allwinner A20 boards. In the end I found these magic register pokes in the cubietruck kernel tree: https://github.com/cubieboard2/linux-sunxi/commit/7f08ba395617d17e7a711507503d89a50406fe7a This is also done for the bcm43362 in broadcom's internal/proprietary driver.

Hope you still have the whole series somewhere. This patch replaces the one with: Message-ID: <1404051421-24377-5-git-send-email-hdegoede@xxxxxxxxxx> It applies to the master branch of the wireless-next repository.
