Change subject: purism/librem13: Disable L1 sub states support ......................................................................
Patch Set 3:
Please make this run-time configurable for people not having such a problematic device.
What do you mean exactly? I only disable it for librem13 v1 boards which has the issue. A user can still enable it manually if they wish it, but by default it's disabled. Every other broadwell board will have it enabled by default.
