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.
