Subject: [PATCH] drm/i915: Update i915.reset to handle engine resets
Git-commit: ed35dd7b259f10bff34e64847995f291ae8b490c
Patch-mainline: v4.14-rc1
References: FATE#322643 bsc#1055900
In preparation for engine reset work update this parameter to handle more
than one type of reset. Default at the moment is still full gpu reset.
