Subject: [PATCH 0/2] Ignore Energy Model with abstract scale in IPA and DTPM

Hi all,

The Energy Model supports abstract scale power values. This might cause
issues for some mechanisms like thermal governor IPA or DTPM, which
expect that all devices provide sane power values. This patch set prevents
from registering such devices for IPA and DTPM.

Regards,
Lukasz
