Add the driver to monitor Wisreon power supplies with hwmon over pmbus.


Hi Ben.


This driver looks very similar to the IBM CFFPS driver. If you think they are similar enough, you may want to simply add a new version to that driver that supports your PSU.


It would be nice to have datasheets for those power supplies.

Eddie - is it possible that the IBM power supply supports the WRITE_PROTECT
command and has a write protect bit set ? If yes, I just submitted a patch
for the PMBus core to address the situation; see

Thanks,
