| * watchdog: Add Xilinx watchdog timer driverAlejandro Cabrera2011-07-263-0/+450
| | | | | | | | | | | | | | | | | | | | | | | | Watchdog timer device driver for Xilinx xps_timebase_wdt compatible ip cores. It takes watchdog timer configuration from device tree and it needs that its parent has defined the property "clock-frecuency". It is compatible with watchdog timer kernel API, so user apps like watchdogd may talk with it. Signed-off-by: Alejandro Cabrera <aldaya@gmail.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
| * watchdog: remove empty pm-functionsWolfram Sang2011-07-263-29/+0
| | | | | | | | | | | | | | | | | | | | | | While checking what watchdog drivers usually do in suspend/resume to spot common behaviour for the watchdog framework, I found these drivers which do nothing but add some cruft. Remove it, it is superfluous. New approaches should probably be done with pm_ops anyway. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
| * watchdog: sp805: Flush posted writes in enable/disable.Nick Bowler2011-07-261-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are no reads in these functions, so if MMIO writes are posted, the writes in enable/disable may not have completed by the time these functions return. If the functions run from different CPUs, it's in theory possible for the writes to be interleaved, which would be disastrous for this driver. At the very least, we need an mmiowb() before releasing the lock, but since it seems desirable for the watchdog timer to be actually stopped or reset when these functions return, read the lock register to force the writes out.

| * watchdog: sp805: Don't write 0 to the load value register.Nick Bowler2011-07-261-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least on the Versatile Express' V2M, calling wdt_disable followed by wdt_enable, for instance by running the following sequence: echo V > /dev/watchdog; echo V > /dev/watchdog results in an immediate reset. The wdt_disable function writes 0 to the load register; while the watchdog interrupts are disabled at this point, this special value is defined to trigger an interrupt immediately. It appears that in this instance, the reset happens when the interrupts are subsequently enabled by wdt_enable. Putting in a short delay after writing a new load value in wdt_enable solves the issue, but it seems cleaner to simply never write 0 to the load register at all: according to the hardware docs, writing 0 to the control register suffices to stop the counter, and the write of 0 to the load register is questionable anyway since this register resets to 0xffffffff.

| * watchdog: pc87413_wdt: Cleanup pc87413 watchdog driver to useJonathan McDowell2011-07-221-46/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inspired by Nat Gurumoorthy's recent patches for cleaning up the it87 drivers to use request_muxed_region for accessing the SuperIO area on these chips, and the fact I have a GPIO driver for the pc8741x basically ready for submission, here is a patch to cleanup the pc87413 watchdog driver to use request_muxed_region for accessing the SuperIO area. It also pulls out the details about the SWC IO area on initial driver load, and properly does a request_region for that area - there's no requirement to touch the SuperIO area after doing the initial watchdog enable and IO base retrieval. While I have hardware with a pc87413 on it it is not wired in a way that allows the watchdog to reboot the machine, so I have not been able to fully test these changes - I have checked that the driver correctly initialises itself still and requests the SWC io region ok.

| * watchdog: Use "request_muxed_region" in it87 watchdog driversNat Gurumoorthy2011-07-222-95/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes the it87 watchdog drivers to use "request_muxed_region". Serialize access to the hardware by using "request_muxed_region" macro defined by Alan Cox. Call to this macro will hold off the requestor if the resource is currently busy. The use of the above macro makes it possible to get rid of spinlocks in it8712f_wdt.c and it87_wdt.c watchdog drivers. This also greatly simplifies the implementation of it87_wdt.c driver. "superio_enter" will return an error if call to "request_muxed_region" fails. Rest of the code change is to ripple an error return from superio_enter to the top level.

| | | | | | | | | | | | | | | | | | | Commit e391be76 (MIPS: Alchemy: Clean up GPIO registers and accessors) changed the way the GPIO was toggled. Prior to this patch, we would always actively drive the GPIO output to either 0 or 1, this patch drove the GPIO active to 0, and put the GPIO in tristate to drive it to 1, unfortunately this does not work, revert back to active driving. Using a signed variable (gstate) to hold the gpio state and using a bit- wise operation on it also resulted in toggling value from 1 to -2 since the variable is signed. This value was then passed on to gpio_direction_ output, which always perform a if (value) ... to set the value to the gpio, so we were always writing a 1 to this GPIO instead of 1 -> 0 -> 1 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | reboot on timer expiry This is needed for determining the reason for failure when a softdog timeout occurs. We use softdog to watch for critical application failures and at the minimum a snapshot of the system would help to determine the cause. In such a scenario the application could fail but there isn't a softlockup as such, hence the detect softlockup feature does not help. The patch adds a module parameter soft_panic which when set to 1 causes softdog to invoke panic instead of reboot when the softdog timer expires. By invoking panic we execute kdump if it is configured and the vmcore generated by kdump should provide atleast a minimal idea of the reason for failure.

|/ | | | | | | | | | | Use mfd_data for passing information from mfd drivers to soc clients. The mfd_cell's driver_data field is being phased out.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The omap_wdt should only be in full active state when the registers are being accessed.

When the watchdog is enabled, the timeout is displayed as a number of seconds, instead of an obscure "period". The "period" is the position of a bit in a 64-bit timer register. The higher the value, the quicker the watchdog timeout occurs. Some people chose a high "period" value for the timer and get confused as to why the board resets within a few seconds. Messages displayed during open and close are now debug messages, so that they don't clutter the console by default. Finally, printk() is replaced with the pr_xxx() equivalent.
