Subject: [PATCH v4 5/5] arm64: dts: qcom: msm8996: Add interconnect support
Add interconnect providers for the multiple NoCs available on the platform,
and assign interconnects used by some blocks.
Signed-off-by: Yassine Oudjana <y.oudjana@...tonmail.com>
---
Changes since v2:
- Remove interconnect paths from CPUs since cpufreq driver doesn't support icc scaling yet.
