- Drop assignments to otherwise unused variables
- Drop empty remove function
This also drops the inaccurate message on remove; the driver won't be
removed if the hardware watchdog is running, no matter if the watchdog
device is open or not.
- Use local variable 'struct device *dev' consistently
- Use devm_watchdog_register_driver() to register watchdog device

Introduce local variable 'struct device *dev' and use it instead of
dereferencing it repeatedly. Also, there is no call to dev_get_drvdata()
or platform_get_drvdata() in the driver, so drop the unnecessary
call to platform_set_drvdata().

The get_timeleft call for wdat_wdt was using ACPI_WDAT_GET_COUNTDOWN
when running an action on the device, which would return the configured
countdown, instead of ACPI_WDAT_GET_CURRENT_COUNTDOWN, which returns the
time left before the watchdog will fire. This change corrects that.

The driver registers the watchdog with devm_watchdog_register_device() but
still calls watchdog_unregister_device() on remove. Since clocks have to
be stopped when removing the driver, after the watchdog device has been
unregistered, we can not drop the call to watchdog_unregister_device().
Use watchdog_register_device() to register the watchdog.

This adds a minimal support for booting IXP4xx systems
from device tree.
We have to add hacks to the QMGR, NPE and notably also
ethernet and watchdog drivers so that they don't crash
the platform: these drivers are unconditionally starting
to grab regions of statically remapped IO space with no
concern of the device model or other platforms.
We will go in and properly fix these drivers as we go
along but for now this hack gets us to a place where we
can start working on proper device tree support for these
platforms.

cases where we are expecting to fall through.
This patch fixes the following warning:

Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

Introduce watchdog driver for a various range of Mellanox Ethernet and
Infiniband switch systems.
Watchdog driver for Mellanox watchdog devices, implemented in
programmable logic device.
Main and auxiliary watchdog devices can exist on the same system.
There are several actions that can be defined in the watchdog:
system reset, start fans on full speed and increase a counter.
The last 2 actions are performed without a system reset.
Actions without reset are provided for auxiliary watchdog devices,
which is optional.
Access to HW registers is performed through generic
regmap interface.
There are 2 types of HW watchdog implementations.
Type 1: actual HW timeout can be defined as power of 2 msec.
e.g. timeout 20 sec will be rounded up to 32768 msec.;
maximum timeout period is 32 sec (32768 msec.);
get time-left isn't supported
Type 2: actual HW timeout is defined in sec. and it's the same as
user-defined timeout;
maximum timeout is 255 sec;
get time-left is supported;
Watchdog driver is probed from the common mlx_platform driver.

for 5.1, please pull the following:
- Stefan updates the BCM2835 SoC driver with downstream properties and
uses that to implement a reboot notifier to tell the VC4 firmware when
Linux on the ARM CPU is rebooting
- Eric adds a proper power domain driver for the BCM283x SoCs and
updates a bunch of drivers to have a better and clearer Device Tree
definition to support power domains/breaking up of functionality. This
requires converting the existing watchdog driver into a MFD and then
breaking up the functionality into separate drivers and finally
updating the DTS files to leverage the power domains information.
- Wei provides a fix for making a symbol static

This adds the support for qcom watchdog suspend and resume
when entering and exiting deep sleep states. Otherwise
having watchdog active after suspend would result in unwanted
crashes/resets if resume happens after a long time.

The PM block that the wdt driver was binding to actually has multiple
features we want to expose (power domains, reset, watchdog). Move the
DT attachment to a MFD driver and make WDT probe against MFD.
