[PATCH ath-next 00/17] wifi: ath12k: Add support for QCN6432
From: Aaradhana Sahu
Date: Thu Oct 08 2026 - 06:25:24 EST
QCN6432 is a PCIe-based device attached to the WCSS Q6 processor. It is
registered as a platform device (AHB), and remoteproc APIs are used to
boot and shut down the device, similar to other AHB-based devices such
as IPQ5332.
However, PCI APIs are used for device setup and register access. Since
QCN6432 requires both AHB and PCI APIs for its operation, a hybrid
AHB/PCI approach is implemented.
Overview:
- Patch [1/17] adds DT binding documentation for QCN6432.
- Patch [2/17] refactors PCI operations and MSI config structure to
support different MSI configurations.
- Patches [3,4,5/17] add hardware parameters, ring mask, and registers
for QCN6432.
- Patch [6/17] moves multi MSI vector flag to ath12k_dev_flags.
- Patches [7,8/17] add hybrid_bus_type and HIF operations support for
QCN6432.
- Patch [9/17] adds support for unified data-region memory allocation.
- Patch [10/17] moves MSI config to pcic for better abstraction.
- Patches [11,12/17] enable MSI interrupt support for CE and DP rings
specific to QCN6432.
- Patch [13/17] uses CMEM write for PPT on hybrid bus devices.
- Patch [14/17] stores and uses per CE DP MSI data for QCN6432.
- Patch [15/17] derives QMI service instance ID per protection domain.
- Patch [16/17] add userpd ID mapping per device.
- Patch [17/17] adds support for QCN6432 in the driver.
