Thanks for the information. I have updated wiki/Devices to reflect this
change for the ADT7475.

I fear that this change will affect pretty much all the hardware
monitoring chips originally designed and sold by Analog Devices. Even
the old ADM1022, ADM1024, ADM1026, ADM1027 etc. have been removed from
the Analog Devices website. These 3 pages on the ON Semiconductor
website seem to cover pretty much all the hardware monitoring chips of
Analog Devices:

We will have to update all the links on the wiki/Devices pages, and
ideally we would also update the references in the source code of all
related drivers. This is a non-trivial amount of work, volunteers are
