Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)//
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
e = devm_ioremap_resource(e1, res);

This patch is being created to use the UEFI bits in the type 219 SMBIOS
record in order to decide whether or not to execute BIOS code. This is a
better solution than to depend on the iCRU bit since not all future servers

The bits in BRIDGE_CAUSE are documented as RW0C - read, write 0 to
clear. If we read the register, mask off the watchdog bit, and
write it back, we're actually clearing every interrupt which wasn't
pending at the time we read the register - and that is racy.Fix this to only write ~WATCHDOG_BIT to the register, which means
we write as zero only the watchdog bit.Signed-off-by: Russell King

The watchdog infrastructure in Dove is no different from that in
Orion5x or Kirkwood, so let's enable it for Dove. The only things
missing are a few register settings in Dove's bridge-regs.h.Rather than duplicating the same register bit masks for the RSTOUTn_MASK
and BRIDGE_CAUSE registers, move the definitions into the watchdog
driver itself.Signed-off-by: Russell King

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

A watchdog device may be stopped from userspace using WDIOC_SETOPTIONS
ioctl and flag WDIOS_DISABLECARD. If the device is closed after this
operation, watchdog_release() is called and status bits checked for
stopping it. Besides, if the device has not been unregistered a critical
message "watchdog did not stop!" is printed, although the ioctl may have
successfully stopped it already.Without the patch a user application sample code like this will successfully
stop the watchdog, but the kernel will output the message
"watchdog did not stop!":wd_fd = open("/dev/watchdog", O_RDWR);
flags = WDIOS_DISABLECARD;
ioctl(wd_fd, WDIOC_SETOPTIONS, &flags);close(wd_fd);
