Mahua is a derivative of the Glymur SoC and shares a significant
portion of its interconnect topology with Glymur. As such, this
series extends the existing Glymur interconnect driver to support
Mahua, reusing common definitions where possible and adding
SoC-specific configurations where necessary.
Device tree changes aren't part of this series and will be posted
separately.
---
Changes in v2:
- Reuse the Glymur device data for Mahua and override with Mahua
specific values [Dmitry]
- Update the commit text to be imperative [Dmitry]
- Link to v1: https://lore.kernel.org/r/20260123-mahua_icc-v1-0-bc82cb087f1e@oss.qualcomm.com

Document the RPMh Network-on-Chip (NoC) interconnect for the Qualcomm
Mahua platform.
Mahua is a derivative of the Glymur SoC. Many interconnect nodes are
identical and continue to use Glymur fallback compatibles. Mahua
introduces SoC-specific configurations and topologies for several
NoC blocks, including CNOC, HSCNOC, PCIe West ANoC/Slave NoCs.
This updates the existing Glymur yaml schema to include Mahua-specific
compatible strings, using two-cell "fallback" compatibles wherever
the hardware is identical with Glymur.

Mahua is a derivative of the Glymur SoC. Extend the
Glymur driver to support Mahua by:
1. Adding new node definitions for interconnects that differ from Glymur
(Config NoC, High-Speed Coherent NoC, PCIe West ANOC/Slave NoC).
2. Reusing existing Glymur definitions for identical NoCs.
3. Overriding the channel and buswidth, with Mahua specific values for
the differing NoCs
