I tested this series on an SDM845 board. Temperatures can be read from
the tsens0 sensors, however for tsens1 sensors I get:
cat temp
cat: temp: No data available
TRDY_READY_BIT set when reading TRDY_OFFSET in get_temp_tsens_v2().
Unfortunately I currently have no documentation of the registers or the
thermal sensors in general and couldn't investigate further.
Any idea what could be the problem?
Thanks
Matthias
