Subject: [PATCH v5 0/3] Add support for clock controllers and CPU scaling
 for QCS615

Add the video, camera, display and gpu clock controller nodes and the
cpufreq-hw node to support cpu scaling.

Clock Dependency:
https://lore.kernel.org/all/20250702-qcs615-mm-v10-clock-controllers-v11-0-9c216e1615ab@quicinc.com

Changes in v5:
- Update the documentation for CPUFREQ-HW for QCS615.
- Update the device tree node for cpufreq-hw to point to the new compatible.
- Link to v4: https://lore.kernel.org/r/20250625-qcs615-mm-cpu-dt-v4-v4-0-9ca880c53560@quicinc.com

Changes in v4:
- Fix the typo(removal of "") from cpufreq-hw node
- Link to v3: https://lore.kernel.org/r/20250612-qcs615-mm-cpu-dt-v3-v3-0-721d5db70342@quicinc.com

Changes in v3:
- Move the cpufreq-hw node under /soc {}
- Add the RB-tag on (v2) from [Konrad]

Changes in v2:
- pad address field to 8 digits [Dmitry]
- Replace cpu/CPU in commit [Dmitry]
- Update the binding to use SC7180 compatible, as QCS615 uses the same
  hardware version.
- Link to v1: https://lore.kernel.org/r/20241108-qcs615-mm-dt-nodes-v1-0-b2669cac0624@quicinc.com
