[v3,00/13] wifi: ath12k: add Ath12k AHB driver support for IPQ5332

Currently, Ath12k driver only supports WiFi devices that are based on
PCI bus. New Ath12k device IPQ5332 is based on AHB bus. Hence, add
Ath12k AHB support for IPQ5332.

IPQ5332 is IEEE802.11be 2 GHz 2x2 Wifi device. To bring-up IPQ5332
device:
- Add hardware parameters for IPQ5332.
- CE register address space in IPQ5332 is separate from WCSS register
  space. Hence, add logic to remap CE register address.
- Add support for fixed QMI firmware memory for IPQ5332.
- Support userPD handling for WCSS secure PIL driver to enable ath12k
  AHB support.

v3:
- DT binding: clock name changed from gcc_xo_clk to xo.
- DT binding: Upper constraint added for memory-region property.
- DT binding: The description for "qcom,rproc" phandle updated to represent
  the hardware aspect.
- DT binding: Added property qcom,ath12k-calibration-variant.
- Squashed patch[2/22] to patch[8/22] of v2 into a single patch.
- Patch reordering is done.
- The hardware parameter "m3_fw_support" renamed to "needs_m3_fw".
- CMEM remap and CMEM register handling are dropped. CMEM registers are
  accessed within WCSS register space (ab->mem).
- The devm APIs are used for interrupts handling.
- Logic updated in ath12k_ahb_map_service_to_pipe().
- Dependency path series from other subsystem are dropped.

v2: https://lore.kernel.org/all/20241015182637.955753-1-quic_rajkbhag@quicinc.com/
- "qcom,board_id" property is dropped. This is not the direct dependency
  for Ath12k AHB support, hence it can be taken up separately.
- "qcom,bdf-addr" property is dropped in device-tree and moved to ath12k
  driver.
- Currently we have only one compatible enum (qcom,ipq5332-wifi), hence
  conditional if() check for defining the binding is removed.
- "reserved-memory" node is dropped from example DTS.
- "status" property is dropped in wifi node of example DTS.
- Integrated the “Support userPD handling for WCSS secure PIL driver”
  patch series with the Ath12k AHB bring-up patch.
- Removed the RFC tag as all dependency patch series are now compilable.

Missed to include "devicetree@vger.kernel.org". I have now sent v4 with all
the list as per - scripts/get_maintainer.pl
