Hi, no I haven't tried it, I can give it a try tomorrow when I have access to my board and see whats going wrong, but I did look at Andys for-next and the defconfig still does not have either nvmem or qcom-qfprom drivers enabled. Did you manually enable them? or are you seeing this with the drivers still disabled?
