I added Fixes tag to the last patch but not stable tag because the other two patches it depends are not really stable material IMO. Please let me know if there is a better way to organize these :) I tested this on Intel Whiskey Lake based system (CNL derived) and on Comet Lake-V based system (SPT derived and the iTCO_wdt still works and I can see the expected resources in /proc/ioports and /proc/iomem.
