SDM845 has two tsens blocks, one with 13 sensors and the other with 8
sensors.

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

These unit addresses should match the first reg property, not the second
one.

Strangely enough, I'm seeing this now after rebuilding my integration
branch to test some other bits.

I've sent another version with this patch removed while I investigate
this. Could you check if you're able to read all 8 sensors with v5?

Amit

Fixed in v5. Thanks.

With v6 all sensors can be read, thanks!

Great! Would it be OK to add your Tested-by tag?
