Subject: [RFC PATCH v2 0/5] wifi: ath12k: Add WSI node for QCN9274 in RDP433 for MLO

The RDP433 is a Qualcomm Reference Design Platform based on the
IPQ9574. It features three QCN9274 WiFi devices connected to PCIe1,
PCIe2, and PCIe3. These devices are also interconnected via a WLAN
Serial Interface (WSI) connection. This WSI connection is essential
to exchange control information among these devices.

This patch series describes the WSI interface found in QCN9274 and
uses this device-tree node in the Ath12k driver to provide details
of details of WSI connection for in Multi Link Operation (MLO) among
multiple QCN9274 devices.

NOTES:
1. As ath12k MLO patches are not ready yet, this patchset does not apply
   to the ath.git ath-next branch and that's why the patchset is marked
   as RFC. These are the work-in-progress patches we have at the moment.
   The full set of MLO patches is available at:
   https://git.kernel.org/pub/scm/linux/kernel/git/ath/ath.git/log/?h=ath12k-mlo-qcn9274

2. The dependency marked below applies only to the DTS patch. The
   dt-bindings patches do not have this dependency.

Depends-On: [PATCH V7 0/4] Add PCIe support for IPQ9574
Link: https://lore.kernel.org/linux-pci/20240801054803.3015572-1-quic_srichara@quicinc.com/

v2:
- "Graph with endpoint” is used to define the actual WSI connection in
  the DT binding.
- The qcom,wsi-index and qcom,wsi-num-devices properties are dropped
  from the binding. These are now determined in the driver using the
  graph with endpoint.
- The qcom,wsi-master property is added to the binding to define the
  WSI master.
- The qcom,ath12k-calibration-variant property is added to the binding
  for ath12k devices.
- DTS changes are made based on the “graph with endpoint” binding.
- The ath12k driver is updated to read graph nodes, determine the number
  of devices in WSI, and assign the wsi-index for each device.
- The ath12k driver now assigns hardware link IDs based on the order of
  WSI connections.
