There is no pinctrl "gpio" and "otpout" (probably designed as "output") handling in the tsadc driver. Let's use proper binding "default" and "sleep".
This looks reasonable, however I've tried it on my Radxa Rock 5C and the driver still doesn't claim GPIO0 RK_PA1 even with this change. As a result, a simulated thermal runaway condition (I've changed the tshut temperature to 65000 and tshut mode to 1) doesn't trigger a PMIC reset, even though a direct `gpioset 0 1=0` does.
Are any additional changes needed to the driver itself?
I've been digging through this patch the whole TSADC/OTP thing in the last couple of hours, and AFAIK some parts of the upstream driver are still missing, in comparison with the downstream driver.
I've got some small suggestions for the patch itself, but the issue you observed is obviously of higher priority, and I've singled it out as well while digging through the code.
Could you, please, try the patch below quickly, to see is it going to fix the issue you observed? I've got some "IRL stuff" to take care of today, so I can't test it myself, and it would be great to know is it the right path to the proper fix.

If you could test it, please, it would be great, and I'd prepare the proper patch tomorrow or so.
