* mv watchdog tree under driversWim Van Sebroeck2007-10-181-326/+0
| | | | | | move watchdog tree from drivers/char/watchdog to drivers/watchdog. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: Rework the timeout register manipulationDale Farnsworth2007-07-241-36/+54
| | | | | | | | | | | | | Consolidate the timeout config register modification into a single function. Also, use the enabled flag in the config register to determine whether the timer is enabled instead of a separately maintained flag, MV64x60_WDOG_FLAG_ENABLED. Add spinlock protection around enabling/disabling the watchdog timer. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: disable watchdog timer when driver is probedDale Farnsworth2007-07-241-0/+2
| | | | | | | | Make sure that we disable the watchdog at start-up. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: Support the WDIOF_MAGICCLOSE featureDale Farnsworth2007-07-241-4/+24
| | | | | | | | | Disallow disabling of the watchdog timer unless a particular character ('V') was recently written to the watchdog device. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: Add a module parameter to change nowayout settingDale Farnsworth2007-07-241-3/+9
| | | | | | | | | | Also, use the WATCHDOG_NOWAYOUT macro, rather than #ifdefs, and use __module_get to prevent module unloading if WATCHDOG_NOWAYOUT is set. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: Add WDIOC_SETOPTIONS ioctl supportDale Farnsworth2007-07-241-1/+10
| | | | | | | | | Allow the watchdog timer to be enabled or disabled via the WDIOC_SETOPTIONS ioctl. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: Support for WDIOC_SETTIMEOUT ioctlDale Farnsworth2007-07-241-7/+31
| | | | | | | | Add the ability to modify the watchdog timer timeout interval. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: Fix WDIOC_GETTIMEOUT return valueDale Farnsworth2007-07-241-3/+1
| | | | | | | | WDIOC_GETTIMEOUT returns seconds, not jiffies. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: Check return value of nonseekable_openDale Farnsworth2007-07-241-3/+1
| | | | | | | | Return the value of the nonseekable_open function and not 0. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: Add arch/powerpc platform supportDale Farnsworth2007-07-241-1/+1
| | | | | | | | Add support for arch/powerpc, specifically for the prpmc2800 platform. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] mv64x60_wdt: Get register address from platform dataDale Farnsworth2007-07-241-5/+16
| | | | | | | | | | | | Previously, the address of the watchdog timer registers was retrieved by calling a global function, mv64x60_get_bridge_vbase(). That function doesn't exist in arch/powerpc. Instead, we now get the register address from a platform data resource and ioremap the registers within the driver.

* [WATCHDOG] mv64x60_wdt: set up platform_device in platform codeDale Farnsworth2007-07-241-25/+1
| | | | | | | | | | | The driver previously registered its platform device data in its own init function--that's bogus. Move that code to platform-specific code in arch/ppc. This is being done so that the platform code can decide at runtime whether to initialize this driver or not.

* [WATCHDOG] use ENOTTY instead of ENOIOCTLCMD in ioctl()Samuel Tardieu2006-10-021-1/+1
| | | | | | | | | | | | | Return ENOTTY instead of ENOIOCTLCMD in user-visible ioctl() results The watchdog drivers used to return ENOIOCTLCMD for bad ioctl() commands. ENOIOCTLCMD should not be visible by the user, so use ENOTTY instead.

* [PATCH] make more file_operation structs staticArjan van de Ven2006-07-031-1/+1
| | | | | | | | | | | | Mark the static struct file_operations in drivers/char as const. Making them const prevents accidental bugs, and moves them to the .rodata section so that they no longer do any false sharing; in addition with the proper debug option they are then protected against corruption..

| | | | | | | | | mv64x600_wdt: convert to the new platform device interface Do not use platform_device_register_simple() as it is going away. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [DRIVER MODEL] Convert platform drivers to use struct platform_driverRussell King2005-11-091-10/+10
| | | | | | | | | This allows us to eliminate the casts in the drivers, and eventually remove the use of the device_driver function pointer methods for platform device drivers. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
* [WATCHDOG] adds device_driver .owner fieldWim Van Sebroeck2005-11-011-0/+1
| | | | | | | | | Initialise the .owner field of the device driver with the module that owns it, for easier tracking of device driver ownership. (probably also better for sysfs...) Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* Create platform_device.h to contain all the platform device details.Russell King2005-10-291-0/+2
| | | | | | | | Convert everyone who uses platform_bus_type to include linux/platform_device.h. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] mv64x60_wdt __user annotations and cleanupsAl Viro2005-09-291-7/+7
| | | | | | | | | | | | | | - use nonseekable_open() instead of messing with if (*ppos != file->f_pos) return -EISPIPE in ->write() (->read is NULL). - trivial __user annotations Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
