please keep the list of nodes sorted by register address. So when looking at 
my v3.18-next/dts branch, it should be after uart4: serial at ff1c0000 and before 
usb_host0_ehci: usb at ff500000 .

After looking this up in the schematics I see that this is the 
overtemperature-protection output pin ... labeled OTP_OUT.
So I'd think the pinconfig should reflect this pin-name, especially as tsadc-int 
suggests, that this would be an interrupt leading into the tsadc, while in 
fact it is an output to a separate circuit.
