[PATCH 0/2] hwmon: (lm75) Add NXP P3T1755 support

[Wolfram Sang]

This small series adds support for the above temp sensor. Ultimately, I
want to support it via I3C. But for now, start simple and add I2C
support, so we have something to compare against.

Commit body is entirely missing? What differentiates this device from
the others in the file?

I just sent a RFC/RFT patch converting all chip access code to regmap
to the hwmon list. This should help with adding I3C support. It would
be great if you can have a look.

Thanks,
Guenter

Okay, will add this info.

Thanks, this is really awesome! It surely will help me adding I3C
support. I already sketched multiple paths to handle the regmap problem
of config reg being 8 bits while all other are 16 bits. A custom read
callback was also one option I considered. I will check your patch later
today and base my work on top of it.

All the best,

   Wolfram
