      watchdog: orion: fix compile-test dependencies · d8f1deaa
      由 Arnd Bergmann 提交于 
      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':
orion_wdt.c:(.text.orion_stop+0x28): undefined reference to `atomic_io_modify'
drivers/watchdog/orion_wdt.o: In function `armada375_stop':
orion_wdt.c:(.text.armada375_stop+0x28): undefined reference to `atomic_io_modify'

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

      watchdog: retu: restore MFD dependency · 9ad82f11
      由 Arnd Bergmann 提交于 
      The retu watchdog calls into the respective mfd driver, but fails to
link if that is diabled:

drivers/watchdog/built-in.o: In function `retu_wdt_set_timeout':
ziirave_wdt.c:(.text+0x8c88): undefined reference to `retu_write'
ziirave_wdt.c:(.text+0x8c88): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `retu_write'

ziirave_wdt.c:(.text+0x8cc8): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `retu_write'

This restores the dependency as it was before

      watchdog: db8500: add back prmcu dependency · 9297b652
      由 Arnd Bergmann 提交于 
      When the db8500 watchdog is enabled without the PRCMU, we get a lot of
warnings about duplicate or missing helper functions:

      The kempld watchdog driver requires the respective MFD driver:

      watchdog: sp805: add back AMBA dependency · 3eafee95
      由 Arnd Bergmann 提交于 
      The driver fails to link if ARM_AMBA is disabled:

drivers/watchdog/sp805_wdt.o: In function `sp805_wdt_driver_init':
sp805_wdt.c:(.init.text+0x4): undefined reference to `amba_driver_register'

It seems that the COMPILE_TEST was added in the wrong place, as there
is no architecture dependency, but a bus dependency. This moves
the dependency accordingly.

      watchdog: wm831x watchdog really needs mfd · d0e32fba

      The wm831x watchdog driver can now be built without the wm831x mfd
driver, which results in a link error:

(.text+0x1a9dc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `wm831x_reg_unlock'

This adds back the dependency that was removed. We can still build test
this driver on all architectures by enabling the MFD driver for it first.

      ACPI / watchdog: Add support for WDAT hardware watchdog · 058dfc76
      由 Mika Westerberg 提交于 
      Starting from Intel Skylake the iTCO watchdog timer registers were moved to
reside in the same register space with SMBus host controller.  Not all
needed registers are available though and we need to unhide P2SB (Primary
to Sideband) device briefly to be able to read status of required NO_REBOOT
bit. The i2c-i801.c SMBus driver used to handle this and creation of the
iTCO watchdog platform device.

Windows, on the other hand, does not use the iTCO watchdog hardware
directly even if it is available. Instead it relies on ACPI Watchdog Action
Table (WDAT) table to describe the watchdog hardware to the OS. This table
contains necessary information about the the hardware and also set of
actions which are executed by a driver as needed.

This patch implements a new watchdog driver that takes advantage of the
ACPI WDAT table. We split the functionality into two parts: first part
enumerates the WDAT table and if found, populates resources and creates
platform device for the actual driver. The second part is the driver
itself.

The reason for the split is that this way we can make the driver itself to
be a module and loaded automatically if the WDAT table is found. Otherwise
the module is not loaded.
