This is a follow up from https://lore.kernel.org/lkml/20190227230707.GA28635@roeck-us.net/

It appears that the kernel has only ever used timer0 on the
orion/kirkwood/armada platforms so timer1 appears to be spare on all of
these. Armada-XP and Armada-385 also have timers 2 and 3 which could be
used in a similar way if it is deemed that timer1 should be kept for
some other purpose.

Chris Packham (2):
  watchdog: orion: remove orion_wdt_set_timeout
  watchdog: orion_wdt: use timer1 as a pretimeout
