[PATCH ath-next v5 0/6] wifi: ath12k: Enable IPQ5424 AHB WiFi device

[PATCH ath-next v5 0/6] wifi: ath12k: Enable IPQ5424 AHB WiFi device

[Raj Kumar Bhagat]

Add support for the new ath12k AHB device IPQ5424, as currently, Ath12k
AHB only supports IPQ5332 WiFi devices.

The IPQ5424 is an IEEE 802.11be 2 GHz WiFi device, supporting 4x4
configurations. To enable the IPQ5424 device:
- Add the necessary hardware parameters for IPQ5424.
- Modify the boot-up sequence for ath12k AHB to accommodate the
  requirements of the IPQ5424 device.

---
Changes in v5:
- The mhi_config and current_cc_support hardware parameters are explicitly
  initialized to default values.
- Link to v4: https://lore.kernel.org/r/20260402-ath12k-ipq5424-v4-0-cd1e0f0a6c88@oss.qualcomm.com

Changes in v4:
- DT binding: dropped copyright update as per discussion in v3.
- DT binding: Used DT binding from v2 and retained Acked-by tag.
- Link to v3: https://patch.msgid.link/20260331-ath12k-ipq5424-v3-0-1455b9cae29c@oss.qualcomm.com

Changes in v3:
- DT binding: updated copyright.
- DT binding: Dropped Acked-by tag as copyright is updated.
- Rebased on latest ToT.
- Dropped ath12k_ahb_ops because qcom_mdt_load() and
  qcom_mdt_load_no_init() now have different number of arguments.
- Link to v2: https://lore.kernel.org/all/20250518-ath12k-ipq5424-v2-0-ef81b833dc97@quicinc.com/

Changes in v2:
- DT binding: Removed the redundant example for IPQ5424, as it is similar
  to IPQ5332.
- Added driver probe data structure to eliminate the redundant switch-case
  logic in the ath12k_ahb_probe() function.
- Validation completed, hence changed from RFC to PATCH.
- Link to v1: https://lore.kernel.org/all/20250130051838.1924079-1-quic_rajkbhag@quicinc.com/

[PATCH ath-next v5 2/6] wifi: ath12k: Add ath12k_hw_params for IPQ5424

[Raj Kumar Bhagat]

From: Saravanakumar Duraisamy <quic_saradura@quicinc.com>

Add ath12k_hw_params for the ath12k AHB-based WiFi 7 device IPQ5424.
The WiFi device IPQ5424 is similar to IPQ5332. Most of the hardware
parameters like hw_ops, wmi_init, ring_mask, etc., are the same between
IPQ5424 and IPQ5332, hence use these same parameters for IPQ5424.
Some parameters are specific to IPQ5424; initially set these to
0 or NULL, and populate them in subsequent patches.

[PATCH ath-next v5 3/6] wifi: ath12k: add ath12k_hw_version_map entry for IPQ5424

[Raj Kumar Bhagat]

Add a new ath12k_hw_version_map entry for the AHB based WiFi 7 device
IPQ5424.

Reuse most of the ath12k_hw_version_map fields such as hal_ops,
hal_desc_sz, tcl_to_wbm_rbm_map, and hal_params from IPQ5332. The
register addresses differ on IPQ5424, hence set hw_regs temporarily
to NULL and populated it in a subsequent patch.

[PATCH ath-next v5 6/6] wifi: ath12k: Enable IPQ5424 WiFi device support

[Raj Kumar Bhagat]

From: Sowmiya Sree Elavalagan <sowmiya.elavalagan@oss.qualcomm.com>

Currently, ath12k AHB (in IPQ5332) uses SCM calls to authenticate the
firmware image to bring up userpd. From IPQ5424 onwards, Q6 firmware can
directly communicate with the Trusted Management Engine - Lite (TME-L),
eliminating the need for SCM calls for userpd bring-up.

Hence, to enable IPQ5424 device support, use qcom_mdt_load_no_init() and
skip the SCM call as Q6 will directly authenticate the userpd firmware.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.6-01275-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ5424 hw1.0 AHB WLAN.WBE.1.6-01275-QCAHKSWPL_SILICONZ-1
