Subject: What to set in struct watchdog_device::bootstatus?
Date: Fri, 8 Feb 2019 11:52:31 +0100 [thread overview]
Message-ID: <20190208105230.g33nxiu4r6uqech3@pengutronix.de> (raw)
Hello,
it's unclear to me, which bits I am supposed to set in the bootstatus
member of struct watchdog_device at probe time.
The i.MX watchdog differentiates the following reset causes:
- Power On
- external reset
- watchdog timeout
- software reset using a bit in the watchdog register set
(Not all i.MX variants implement all bits according to the respective
reference manuals.)
Should "Power On" result in setting WDIOF_POWERUNDER?
Should "software reset [...]" result in WDIOF_CARDRESET?
Should "external reset" result in WDIOF_EXTERN1? (I guess that no)
Best regards
Uwe
