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@ff1c0000 and before
usb_host0_ehci: usb@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.
