Guenter Roeck dcbb613fa8 watchdog: bcm2835_wdt: drop platform_set_drvdata
There is no call to platform_get_drvdata() in the driver,
so platform_set_drvdata() is unnecessary and can be dropped.

Georg Hofmann b07e228eee watchdog: imx2_wdt: Fix set_timeout for big timeout values
The documentated behavior is: if max_hw_heartbeat_ms is implemented, the
minimum of the set_timeout argument and max_hw_heartbeat_ms should be used.
This patch implements this behavior.
Previously only the first 7bits were used and the input argument was
returned.

Guenter Roeck 8dd29f1951 watchdog: rtd119x_wdt: Fix remove function
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.

Gustavo A. R. Silva 265d11ccd5 watchdog: alim7101: Mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/watchdog/alim7101_wdt.c: In function ‘fop_ioctl’:
drivers/watchdog/alim7101_wdt.c:279:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   wdt_keepalive();
   ^~~~~~~~~~~~~~~
drivers/watchdog/alim7101_wdt.c:282:2: note: here
  case WDIOC_GETTIMEOUT:
  ^~~~

Notice that, in this particular case, the /* Fall through */
comment is placed at the very bottom of the case statement,
which is what GCC is expecting to find.

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough.

i.MX8QXP is an ARMv8 SoC which has a Cortex-M4 system controller
inside, the system controller is in charge of controlling power,
clock and watchdog etc..

This patch adds i.MX system controller watchdog driver support,
watchdog operation needs to be done in secure EL3 mode via
ARM-Trusted-Firmware, using SMC call, CPU will trap into
ARM-Trusted-Firmware and then it will request system controller
to do watchdog operation via IPC.
