Looks like some sort of tsens crash with a bad regmap_field or something.

Sorry for breaking the boot on 8064. That was one of the platforms that I didn't convert over to regmap (needs more refactoring). I had hoped kernelci would catch any issues but looks like thermal-soc tree entered linux-next quite late and didn't catch this.
Does reverting 3e6a8fb33084 ("drivers: thermal: tsens: Add new operation to check if a sensor is enabled") fix the issue? If so, reverting that commit might be the best course of action since I've started vacations and can't fix this for 8064 in a meaningful amount of time (until 3rd week of June). cc'ing Bjorn in case this needs more investigation, but I think that patch is fairly self contained and reverting it shouldn't have any knock-on effects.
Regards, Amit
