From 858f763c1cc37ecc6ab39dec60bb3a46606dcac4 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 4 Jan 2011 21:28:20 +0100 Subject: MIPS: ath79: add common watchdog device All supported SoCs have a built-in hardware watchdog driver. This patch registers a platform_device for that to make it usable. Signed-off-by: Gabor Juhos Signed-off-by: Imre Kaloz Cc: linux-mips@linux-mips.org Cc: Luis R.
