R40 SoC has touchscreen controller also serving as general-purpose ADC.
The hardware is very similar to A31, except that R40 has separate
calibrated thermal sensor IP (handled by sun8i_thermal).
Despite the temperature sensor in the RTP is never mentioned in
the R40 family user manuals, it appears to be working. However,
it's not very useful as it lacks calibration data and there is another
fully functioning temperature sensor anyway.
This patch disables the temperature sensor in RTP/GPADC IP on R40.
The reason for disabling the temperature sensor is that the IP
needs to be switched back and forth between RTP and GPADC modes for
temperature measurements. Not only this introduces delays, but it also
disturbs external circuitry by injecting current into ADC inputs.

I'm fine with this and assuming Lee is happy to pick it up + send
me an immutable branch in case anything crosses with it this cycle..

Hi Jonathan!
Is there anything else I should do to make this patch series accepted?
Thanks,
