Hi Andrey,

I had to port the LM75 driver to barebox just a few days ago and so came
up with exactly the same patch 2/7 and 3/7. I applied 1-3 right away.

In my case I not only have a LM75 but also a PT100 connected to a
Microchip MCP3421 which in Linux is abstracted as a IIO device. IIO has
the advantage that it's more formalized and has it's own device tree
binding that allows to connect sensor devices with their consumers. I
picked some of the pieces from IIO and created something I called
iodevice. I'll post it in the next few days. One thing I am missing in
your approach is the readout of values as device parameters so that the
values can be evaluated in scripts. On the other hand you have a command
that allows to show the values of all sensors which I currently don't
have. Maybe we can distil the best of both approaches.

Sascha
