Subject[PATCH 0/2] make generic-adc-thermal less noisy
Date
I want to use generic-adc-thermal on the 32-bit Amlogic SoCs in the
future. These have a thermal sensors which can be read through the
SAR ADC (for which we have an IIO driver) on those SoCs.

While testing I found the generic-adc-thermal driver to be a bit
noisy when operating in well supported environment:
- the SoC temperature sensor on the 32-bit Amlogic SoCs is typically
loaded late because of it's dependencies (it needs data from the
eFuse and a syscon to calibrate). Yet I still got a message stating
there's no lookup table for the generic-adc-thermal defined (which
is expected and perfectly valid on these Amlogic SoCs, as the IIO
channel returns the temperature).
- the IIO channel is correctly defined with type IIO_TEMP, yet the
generic-adc-thermal driver still prints a message which first lead
me to believe that I passed an incorrect IIO channel (one that
returns a voltage).

thermal: generic-adc: silence "no lookup table" on deferred probe
thermal: generic-adc: silence info message for IIO_TEMP channels
