Would you be able to have a look at this binding? The driver won't be
upstreamed as hwmon driver (as per Guenter's comments). I am currently
converting the driver to a "soc" driver instead, but the proposed
binding remains unchanged.
If you have comments or suggestions, I would like to incorporate them
with the new series I will be sending out.
Thanks,
-Markus
