Message-Id: <1444163325-3041-1-git-send-email-sylvain.rochet@finsecur.com> Date: Tue, 6 Oct 2015 22:28:45 +0200 From: Sylvain Rochet <sylvain.rochet@...secur.com> To: Guenter Roeck <linux@...ck-us.net>, Alexandre Belloni <alexandre.belloni@...e-electrons.com>, Boris BREZILLON <boris.brezillon@...e-electrons.com>, linux-kernel@...r.kernel.org, Nicolas Ferre <nicolas.ferre@...el.com>, Ludovic Desroches <ludovic.desroches@...el.com>, linux-arm-kernel@...ts.infradead.org Cc: Sylvain Rochet <sylvain.rochet@...secur.com>, <stable@...r.kernel.org> Subject: [PATCH] watchdog: at91sam9: keep watchdog running in idle mode Since turning on idle-halt in commit 5161b31dc39a (watchdog: at91sam9_wdt: better watchdog support"), SoCs compatible with at91sam9260-wdt not using a device tree no longer reboot if the watchdog times out while the CPU is in idle state. Removing the AT91_WDT_WDIDLEHLT flag that was set by default fixes this.
