From 6e63a3a294fdf91eaaac1061a9c7a5f53d16ac25 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Wed, 19 Jun 2013 20:38:58 +0530 Subject: watchdog: delete mpcore_wdt driver Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu interrupt (usually interrupt #30), and the GIC configuration should flag it as such. With this setup, request_irq() should fail, and the right API is request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq(). Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the right CPU. There are no users of this driver since a long time and it makes more sense to get rid of it as nobody is looking to fix it. In case somebody wakes up after this has been removed and needs it, please revert this driver and pick these updates (These were never pushed to mainline): http://comments.gmane.org/gmane.linux.ports.arm.kernel/245998 Signed-off-by: Viresh Kumar Acked-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck --- arch/arm/configs/spear13xx_defconfig | 1 - 1 file changed, 1 deletion(-) (limited to 'arch') diff --git a/arch/arm/configs/spear13xx_defconfig b/arch/arm/configs/spear13xx_defconfig index 1fdb82694ca..82eaa552ed1 100644 --- a/arch/arm/configs/spear13xx_defconfig +++ b/arch/arm/configs/spear13xx_defconfig @@ -61,7 +61,6 @@ CONFIG_GPIO_SYSFS=y CONFIG_GPIO_PL061=y # CONFIG_HWMON is not set CONFIG_WATCHDOG=y -CONFIG_MPCORE_WATCHDOG=y # CONFIG_HID_SUPPORT is not set CONFIG_USB=y # CONFIG_USB_DEVICE_CLASS is not set -- cgit v1.2.3-18-g5258
