      watchdog: fix compile time error of pretimeout governors · d6c80b60
      由 Vladimir Zapolskiy 提交于 
      [ Upstream commit a223770bfa7b6647f3a70983257bd89f9cafce46 ]

CONFIG_WATCHDOG_PRETIMEOUT_GOV build symbol adds watchdog_pretimeout.o
object to watchdog.o, the latter is compiled only if CONFIG_WATCHDOG_CORE
is selected, so it rightfully makes sense to add it as a dependency.

The change fixes the next compilation errors, if CONFIG_WATCHDOG_CORE=n
and CONFIG_WATCHDOG_PRETIMEOUT_GOV=y are selected:

  drivers/watchdog/pretimeout_noop.o: In function `watchdog_gov_noop_register':
  drivers/watchdog/pretimeout_noop.c:35: undefined reference to `watchdog_register_governor'
  drivers/watchdog/pretimeout_noop.o: In function `watchdog_gov_noop_unregister':
  drivers/watchdog/pretimeout_noop.c:40: undefined reference to `watchdog_unregister_governor'

      watchdog: Add Nuvoton NPCM watchdog driver · 975b7f0f
      由 Joel Stanley 提交于 
      The Nuvoton NPCM750 has a watchdog implemented as a single register
inside the timer peripheral.

This driver exposes that watchdog as a standard watchdog device with
coarse timeout intervals, limited by the combination of prescaler and
counter that is provided by the hardware. The calculation is taken from
the Nuvoton vendor tree.

The watchdog is left running if a bootloader had it going. The rate is
the one specified in the device tree, or the default value (obtained
from the datasheet).

There is a pre-timeout IRQ that is wired up. This timeout always occurs
1024 clocks before the timeout.

      watchdog: indydog: Add dependency on SGI_HAS_INDYDOG · 24f8d233
      由 Matt Redfearn 提交于 
      Commit da2a68b3 ("watchdog: Enable COMPILE_TEST where possible")
enabled building the Indy watchdog driver when COMPILE_TEST is enabled.
However, the driver makes reference to symbols that are only defined for
certain platforms are selected in the config. These platforms select
SGI_HAS_INDYDOG. Without this, link time errors result, for example
when building a MIPS allyesconfig.

drivers/watchdog/indydog.o:indydog.c:(.text+0xa8): more undefined
references to `sgimc' follow
make: *** [Makefile:1005: vmlinux] Error 1

Fix this by ensuring that CONFIG_INDIDOG can only be selected when the
necessary dependent platform symbols are built in.

      watchdog: orion: fix compile-test dependencies · d8f1deaa

      I ran into one corner case with the orion watchdog using the
atomic_io_modify interface:

drivers/watchdog/orion_wdt.o: In function `orion_stop':

This function is available on all 32-bit ARM builds except for ebsa110, so
we have to specifically exclude that from compile-testing.
