Subject: [PATCH 0/3] getting more output from orion_wdt
Date: Wed, 11 Oct 2017 15:29:55 +1300 [thread overview]
Message-ID: <20171011022958.31268-1-chris.packham@alliedtelesis.co.nz> (raw)
On the Armada-38x platforms (and probably 37x/XP) the current behaviour of on
exipry of the watchdog is a silent reboot of the CPU. The Armada-38x does have
an interrupt which if we don't enable the Global WD bit in the RSTOUTn register
gives us a chance to generate some panic messages that may help track down the
cause of the watchdog timeout.
I've been a bit bold and enabled this in the generic armada-38x.dtsi file. I'd
be happy to leave that part out and have the interrupt enabled on a
board-by-board basis if there are objections.
Chris Packham (3):
watchdog: orion: fix typo
watchdog: orion: don't enable rstout if an interrupt is configured
ARM: mvebu: dts: connect interrupt for WD on armada-38x
