watchdog: kempld_wdt: Fix bit mask definition

2013-10-18T17:54:57+00:00

commit 4c4e45669de475573b15d968a6dca8d00124c9ad upstream.

STAGE_CFG bits are defined as [5:4] bits. However, '(((x) & 0x30) << 4)'
handles [9:8] bits. Thus, it should be fixed in order to handle
[5:4] bits.

watchdog: ts72xx_wdt: locking bug in ioctl

2013-10-18T17:54:56+00:00

commit 8612ed0d97abcf1c016d34755b7cf2060de71963 upstream.

Calling the WDIOC_GETSTATUS & WDIOC_GETBOOTSTATUS and twice will cause a
interruptible deadlock.

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2013-07-13T21:52:21+00:00

Pull MIPS updates from Ralf Baechle:
 "MIPS updates:

   - All the things that didn't make 3.10.
   - Removes the Windriver PPMC platform.  Nobody will miss it.
   - Remove a workaround from kernel/irq/irqdomain.c which was there
     exclusivly for MIPS.  Patch by Grant Likely.
   - More small improvments for the SEAD 3 platform
   - Improvments on the BMIPS / SMP support for the BCM63xx series.
   - Various cleanups of dead leftovers.
   - Platform support for the Cavium Octeon-based EdgeRouter Lite.

  Two large KVM patchsets didn't make it for this pull request because
  their respective authors are vacationing"

Merge branch '3.10-fixes' into mips-for-linux-next

This that should have been fixed but weren't, way to much, intrusive
and late.

watchdog: hpwdt: Add check for UEFI bits

2013-07-11T20:20:06+00:00

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
will use iCRU.

watchdog: softdog: remove replaceable ping operation

2013-07-11T20:19:30+00:00

In watchdog_ping(), 'start' is called automatically when 'ping' function call
is not configured.
Softdog driver has same handling in both cases - start and ping, so 'ping' OPS
can be removed.

Watchdog: fix clearing of the watchdog interrupt

2013-07-11T20:18:30+00:00

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.

Watchdog: allow orion_wdt to be built for Dove

2013-07-11T20:17:56+00:00

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.
