* [WATCHDOG] misc_register patch Wim Van Sebroeck2008-01-257-60/+60
| | | | | | | | | Make sure that we first do a register_reboot_notifier before we do a misc_register. A misc_register opens the interface to userspace and it's best to do this as the last action. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] wdt: fix lockingAlan Cox2008-01-251-3/+27
| | | | | | | | | | | | | | | | | The audit of _p usage shows various drivers assume inb_p is somehow atomic. Of course it isn't and the delay can be split from the I/O cycle causing a timing violation on chips that matter (eg this one) With the proposed use of udelay() for some _p delays this will cease to be a mostly theoretical bug (as the delay stall is unsplittable) and wants fixing. Lots of other drivers need fixing this way too. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
* [AVR32] Add support for AT32AP7001 and AT32AP7002Haavard Skinnemoen2008-01-251-1/+1
| | | | | | | | | These are derivatives of the AT32AP7000 chip, which means that most of the code stays the same. Rename a few files, functions, definitions and config symbols to reflect that they apply to all AP700x chips, and exclude some platform devices from chips where they aren't present.

* [WATCHDOG] at32ap700x_wdt: add support for boot status and add fix for ↵Hans-Christian Egtvedt2007-11-191-4/+65
| | | | | | | | | | | | | | | | | | | silicon errata This patch enables the watchdog to read out the reset cause after a boot and provide this to the user. The driver will now also return -EIO if probed when booting from a watchdog reset. This is due to a silicon errata in the AT32AP700x devices. Detailed description and work-arounds can be found in the errata section of the datasheet avilable from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | Some watchdog drivers initialize global spinlocks in module's init function which is tolerable, but some do it in PCI probe function. So, switch to static initialization to fix theoretical bugs and, more importantly, stop giving people bad examples.

* [WATCHDOG] Linux kernel IPC SBC Watchdog Timer driverVeljkovic Srdjan2007-10-231-3/+4
| | | | | | | | | | | | | | ICP's Wafer 5823 SBC has, as far as I can tell, the same WDT as many, if not all ICP's SBC's (that do have a WDT). I have tested it with several boards, including Rocky 4783, Rocky 3703 and Rocky 3782. I propose a rename of the Wafer 5823 watchdog timer driver to something like "IPC (SBC) Watchdog Timer", to reflect that it works with other IPC boards (maybe even all of them).
