Wim Van Sebroeck 2786095a58 [WATCHDOG] i6300esb.c: change platform_driver to pci_driver
Since the intel 6300esb platform uses a dedicated PCI ID for
it's watchdog timer (00:1d.4), it's better and easier to have
this as a pci_driver.

Wim Van Sebroeck 39f3be72c1 [WATCHDOG] i6300esb: fix unlock register with
Before you can read or write from the i6300esb memeory mapped registers,
you need to unlock these. This is done by writing the magic numbers 0x80
and 0x86 to the reload register. The size of the reload register is 32bit
though.

Also binary 11 is hex 0x03 and not 0x11.

Wim Van Sebroeck fc8a9d830f [WATCHDOG] i6300esb.c: Restructure initialization of the device
The i6300ESB watchdog should be stopped before userspace has access to the
watchdog. So fix this and restructure the initialization sequence into:
	* See if we have a i6300 device
	* make sure that we have valid module parameters
	* Initialize the device
	* register the /dev/watchdog device so that userspace has access

Arjan van de Ven af4c293ffc [WATCHDOG] pci: use pci_ioremap_bar() in drivers/watchdog
Use the newly introduced pci_ioremap_bar() function in drivers/watchdog.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.

Wim Van Sebroeck 0c06090c94 [WATCHDOG] Coding style - Indentation - part 2
This brings the watchdog drivers into line with coding style.
This patch takes cares of the indentation as described in chapter 1.
Main changes:
* Re-structure the ioctl switch call for all drivers as follows:
	switch (cmd) {
	case WDIOC_GETSUPPORT:
	case WDIOC_GETSTATUS:
	case WDIOC_GETBOOTSTATUS:
	case WDIOC_GETTEMP:
	case WDIOC_SETOPTIONS:
	case WDIOC_KEEPALIVE:
	case WDIOC_SETTIMEOUT:
	case WDIOC_GETTIMEOUT:
	case WDIOC_GETTIMELEFT:
	default:
	}

This to make the migration from the drivers to the uniform watchdog
device driver easier in the future.

Alexey Dobriyan c7dfd0cca3 [WATCHDOG] spin_lock_init() fixes
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.

Jan Engelhardt 96de0e252c Convert files to UTF-8 and some cleanups
* Convert files to UTF-8.

  * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  * Correct town names (Goettingen -> Göttingen)

  * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)
