[v2,0/3] watchdog: orion_wdt: add pretimeout support

Message

It appears that the kernel has only ever used timer0 on the armada platforms so
timer1 appears to be spare on these. Timers 2 and 3 are also free which could
be used if it is deemed that timer1 should be kept for some other purpose.

Chris Packham (3):
  ARM: dts: armada-38x: add interrupts for watchdog
  watchdog: orion: remove orion_wdt_set_timeout
  watchdog: orion_wdt: use timer1 as a pretimeout

Changes in v2:

I've reduced this to just touching the Armada-38x. It would probably
also work on Armada-XP just by adding the appropriate interrupt nodes
to the dts. I don't have access to the Armada-370 datasheet but it'd
likely work there as well..
