Subject: [PATCH v2 00/11] soc/arm64: qcom: Add LLCC BWMON on SDM845

Hi,

Changes since v1
================
1. Patch #2: Drop also BWMON_GLOBAL_IRQ_STATUS (Sibi).
2. Minor rebasings because of above drop.
3. Patch #4: typo in subject (Sibi).
4. New patch: arm64: dts: qcom: sdm845: narrow LLCC address space (Sibi).
5. Add Rb tags.

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.

Qualcomm SoCs might several BWMON instances.  Extend existing support for CPU
BWMON (called v4) to LLCC BWMON (called v5).
