I think Rob wanted something more in the "rockchip-thermal.txt"
document itself.  Like:

Pinctrl states:
- During device probe a driver may glitch the output line.  If this is
not acceptable for your board, you can use the standard "init" and
"default" pinctrl states.  The "init" state will be set before device
probe and "default" after.
