Hi Linus,
Please pull from 'master' branch of
git://www.linux-watchdog.org/linux-watchdog.git
It will fix several Kconfig dependencies, a compilation warning in pcwd_usb,
a failure to abort the sp805 wdt after a ping and the max63xx wdt's MODULE_LICENSE.
This will update the following files:
Kconfig | 6 +++++-
max63xx_wdt.c | 2 +-
pcwd_usb.c | 3 +--
sp805_wdt.c | 5 ++---

watchdog: Fix dependencies for !HAS_IOMEM archs
Not every arch has io memory.
So, unbreak the build by fixing the dependencies.

watchdog: imgdpc: select WATCHDOG_CORE
The imgpdc_wdt driver can be built on all architectures with
CONFIG_COMPILE_TEST, but fails if no other watchdog driver is
enabled:
drivers/watchdog/built-in.o: In function `pdc_wdt_remove':
imgpdc_wdt.c:(.text+0x74): undefined reference to `watchdog_unregister_device'
This adds the normal 'select WATCHDOG_CORE' that is needed to
ensure the driver always builds cleanly.

watchdog: tango: rename ARCH_TANGOX to ARCH_TANGO
This change was requested by arm-soc maintainer Kevin Hilman
because the X in TANGOX is a wildcard.

watchdog: sp805: ping fails to abort wdt reset
sp805 wdt asserts interrupt for the first expiry and
reloads the counter. If wdt interrupt is set and count
reaches zero then wdt reset event is generated. To get
wdt reset at 't' timeout the driver loads wdt counter
with 't/2'. A ping before time 't' *should* prevent
wdt reset. Currently if ping is done after 't/2' then
wdt interrupt condition gets set. On the next countdown
of loadval wdt reset event occurs eventhough wdt was
reloaded before the set timeout 't'.
This patch clears the interrupt condition on ping.
