[PATCH v2 0/2] Clean up MSM8939 interconnect driver

[PATCH v2 0/2] Clean up MSM8939 interconnect driver

[Benjamin Li]

Following up on a review comment on commit 6c6fe5d3dc5e ("interconnect: qcom:
Add MSM8939 interconnect provider driver") to clean up some log pollution.

This is based on icc-next (which appears to contain a refactor commonizing
functions into icc-rpm.c).

v2:
- Update commit message to add a full explanation, rather than referencing a
  previous commit.

[PATCH v2 2/2] interconnect: qcom: msm8939: remove rpm-ids from non-RPM nodes

[Benjamin Li]

Some nodes are incorrectly marked as RPM-controlled (they have RPM
master and slave ids assigned), but are actually controlled by the
application CPU instead. The RPM complains when we send requests for
resources that it can't control. Let's fix this by replacing the IDs,
with the default "-1" in which case no requests are sent.

See commit c497f9322af9 ("interconnect: qcom: msm8916: Remove rpm-ids
from non-RPM nodes") where this was done for msm8916.
