This series adds a hwmon driver to support the OCC on POWER8 and POWER9
processors. The OCC is an embedded processor that provides realtime
power and
thermal monitoring and management.
This driver has two different platform drivers as a "base" for the
hwmon stuff, as the means of communicating with the OCC on P8 and P9 is
completely different. For P8, the driver is an I2C client driver. For
P9 the
driver is an FSI-based OCC client driver, and uses the OCC driver
in-kernel
API.
There was a previous version of this driver that wasn't written with the
differences in communication methods between the two versions in
mind. This
driver has been considerably simplified.
I thought I did see this before.
It is customary to use "v2" in such situations, and add a change log.
You expect me to go into the two versions and compare them to figure
out what changed to evaluate if it makes sense. Do you really believe
that
I have enough time to do that, and that I would be willing to spend that
time in the first place ?
Presumably you know what changed. Why not just tell me ?
Hi,
This driver does not build upon the previous patch set at all, so I
didn't mark it as a v2. It is completely rewritten from scratch. I sent
a note saying that the previous patch set was abandoned. There may be
some similarities with the previous one, simply because the drivers do
the same thing, but I don't think there is any need to compare it with
the old driver I mailed out.
Thanks for your time,
Eddie
