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.. arch/arm/boot/dts/armada-38x.dtsi | 2 + drivers/watchdog/orion_wdt.c | 67 +++++++++++++++++++++++-------- 2 files changed, 52 insertions(+), 17 deletions(-)
