Subject: habanalabs: add 'needs reset' state in driver
X-Git-Tag: accepted/tizen/unified/20230118.172025~8316^2~60^2~33
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=66a76401c50b2638fd95dd31f365fd64be307d6a;p=platform%2Fkernel%2Flinux-rpi.git

habanalabs: add 'needs reset' state in driver

The new state indicates that device should be reset in order
to re-gain funcionality.
This unique state can occur if reset_on_lockup is disabled
and an actual lockup has occurred.
