Subject: [PATCH v3 0/6] interconnect: qcom: Add MSM8996 interconnect driver

This series adds a driver for interconnects on MSM8996. This fixes some rare display underflows
and causes a slight heat reduction.

The driver currently supports all NoCs on MSM8996 except a0noc, due to some issues with writing
to its registers.

Changes since v2:
 - Dual-license qcom,msm8996.h and move it to the dt bindings patch
 - Remove interconnect paths from CPUs since cpufreq driver doesn't support icc scaling yet.
Changes since v1:
 - Split first patch into 2 patches, one for renaming qcom_icc_set in icc-rpmh, and another
   one for the actual commonization.
 - Revert unnecessary move of include line in sdm660.c 

Yassine Oudjana (6):
  interconnect: qcom: icc-rpmh: Rename qcom_icc_set
  interconnect: qcom: sdm660: Commonize RPM-QoS
  dt-bindings: interconnect: Move SDM660 to a new RPM-QoS file
  dt-bindings: interconnect: Add Qualcomm MSM8996 DT bindings
  interconnect: qcom: Add MSM8996 interconnect provider driver
  arm64: dts: qcom: msm8996: Add interconnect support
