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

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.

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,

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,
