Subject: [PATCH v2 0/5] soc/PM/arm64: qcom: Add initial version of bwmon

Hi,

Changes since v1
================
1. Add defconfig change.
2. Fix missing semicolon in MODULE_AUTHOR.
3. Add original downstream (msm-4.9 tree) copyrights to the driver.

Description
===========
BWMON is a data bandwidth monitor providing throughput/bandwidth over certain
interconnect links in a SoC.  It might be used to gather current bus usage and
vote for interconnect bandwidth, thus adjusting the bus speed based on actual
usage.

The work is built on top of Thara Gopinath's patches with several cleanups,
changes and simplifications.

This is "initial version", which means the work is not finished.  The goal is
to add support for further devices (version 5 of bwmon) and usage of devfreq
governors, similarly to tegra30 devfreq driver.

Best regards,
Krzysztof
