Message-Id: <1381031544-2960-4-git-send-email-alan@signal11.us> Date: Sat, 5 Oct 2013 23:52:24 -0400 From: Alan Ott <alan@...nal11.us> To: Alexander Smirnov <alex.bluesman.smirnov@...il.com>, Dmitry Eremin-Solenikov <dbaryshkov@...il.com>, "David S. Miller" <davem@...emloft.net>, david@...weele.net Cc: linux-zigbee-devel@...ts.sourceforge.net, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Alan Ott <alan@...nal11.us> Subject: [PATCH v1 3/3] mrf24j40: Use level-triggered interrupts The mrf24j40 generates level interrupts. There are rare cases where it appears that the interrupt line never gets de-asserted between interrupts, causing interrupts to be lost, and causing a hung device from the driver's perspective. Switching the driver to interpret these interrupts as level-triggered fixes this issue.
