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. NOTE: The working upstream DTS changes for this series have been posted as a separate series. [PATCH v2] arm64: dts: qcom: add wifi node for IPQ5332 based RDP441 v7: - DT binding: DT property 'qcom,ath12k-calibration-variant' renamed to 'qcom,calibration-variant'. v6: https://lore.kernel.org/all/20250225064834.2002499-1-quic_rajkbhag@quicinc.com/ - DT binding: binding doc renamed from qcom,ath12k-ahb.yaml to qcom,ipq5332-wifi.yaml. - DT binding: rephrased memory-region description. - DT binding: dropped description for memory-region-names. - DT binding: updated maintainers in binding doc. - The API ath12k_core_get_reserved_mem_by_name() has been simplified and renamed to ath12k_core_get_reserved_mem() - Removed unnecessary NULL check in devm_clk_get() error handling. - Dropped all ath12k_ahb_clock_* wrappers for single clock. - Removed shutdown callback for the ath12k AHB driver. - Reference count leak handled for rproc and rproc phandle. v5: https://lore.kernel.org/all/20250130043508.1885026-1-quic_rajkbhag@quicinc.com/ - DT binding: Added `memory-region-names` property to address undocumented ABIs. - DT binding: Added four complete items to `memory-region`, required by ath12k firmware. - All calls to `of_find_node_by_name()` are removed. Introduced helper function `ath12k_core_get_reserved_mem_by_name()` to get the reserved memory by name. - Removed unused include headers. - Removed error prints for impossible scenarios. - Used proper phandle API `of_parse_phandle()` to read `qcom,rproc`. - Used `dev_err_probe()` API for logging errors wherever applicable. - Changed hardware parameter `needs_m3_fw` to `enum ath12k_m3_fw_loaders`. - Changed hardware parameter `bdf_addr` to `bdf_addr_offset` to store the offset for BDF memory from the q6-memory as base. v4: https://lore.kernel.org/all/20241210074159.2637933-1-quic_rajkbhag@quicinc.com/ - Missed to include some review list in v3. Hence sending v4 with all review list as per - scripts/get_maintainers.pl v3: https://lore.kernel.org/all/20241209165644.1680167-1-quic_rajkbhag@quicinc.com/ - 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. v1: https://lore.kernel.org/all/20240814094323.3927603-1-quic_rajkbhag@quicinc.com/ Balamurugan S (6): wifi: ath12k: fix incorrect CE addresses wifi: ath12k: add ath12k_hw_params for IPQ5332 wifi: ath12k: avoid m3 firmware download in AHB device IPQ5332 wifi: ath12k: Add hw_params to remap CE register space for IPQ5332 wifi: ath12k: add AHB driver support for IPQ5332 wifi: ath12k: enable ath12k AHB support P Praneesh (1): wifi: ath12k: refactor ath12k_hw_regs structure Raj Kumar Bhagat (2): dt-bindings: net: wireless: describe the ath12k AHB module for IPQ5332 wifi: ath12k: add support for fixed QMI firmware memory Sowmiya Sree Elavalagan (4): wifi: ath12k: Power up root PD wifi: ath12k: Register various userPD interrupts and save SMEM entries wifi: ath12k: Power up userPD wifi: ath12k: Power down userPD .../net/wireless/qcom,ipq5332-wifi.yaml | 315 +++++ drivers/net/wireless/ath/ath12k/Kconfig | 6 + drivers/net/wireless/ath/ath12k/Makefile | 1 + drivers/net/wireless/ath/ath12k/ahb.c | 1155 +++++++++++++++++ drivers/net/wireless/ath/ath12k/ahb.h | 80 ++ drivers/net/wireless/ath/ath12k/ce.c | 92 +- drivers/net/wireless/ath/ath12k/ce.h | 18 +- drivers/net/wireless/ath/ath12k/core.c | 60 +- drivers/net/wireless/ath/ath12k/core.h | 14 +- drivers/net/wireless/ath/ath12k/hal.c | 84 +- drivers/net/wireless/ath/ath12k/hal.h | 68 +- drivers/net/wireless/ath/ath12k/hw.c | 479 ++++++- drivers/net/wireless/ath/ath12k/hw.h | 22 +- drivers/net/wireless/ath/ath12k/pci.c | 10 +- drivers/net/wireless/ath/ath12k/pci.h | 4 +- drivers/net/wireless/ath/ath12k/qmi.c | 208 ++- drivers/net/wireless/ath/ath12k/qmi.h | 3 +- 17 files changed, 2502 insertions(+), 117 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/wireless/qcom,ipq5332-wifi.yaml create mode 100644 drivers/net/wireless/ath/ath12k/ahb.c create mode 100644 drivers/net/wireless/ath/ath12k/ahb.h base-commit: 4d915d21b1229287286f9d400839b65ecaf0e006
