There are few possibilities of the = root cause of this (Cc'ed also to Mark from Lenovo): 1. Bug in firmware: a) wrong pin number; b) wrong pin configuration; c) wrong ASL code that makes 1a) to happen; d) combination of aboves. 2. Bug in the driver. The only possibility so far is the broken offsets for LOCK and/or PADOWN register sets, but the only possible commit that may aff= ect this, i.e. cb8cc18508fb ("pinctrl: tigerlake: Fix register offsets for TGL-H variant"), has been discussed in the bug #213463 comment #9 (also useful to read the entire discussion) and not confirmed to be a culprit. So, to me it sounds quite likely that the issue is on firmware side. But I'm all ears for the information that may help to eliminate it from the equatio= n. --=20 You may reply to this email to add a comment.
