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@xxxxxxxxxxx/ - "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@xxxxxxxxxxx/ 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 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,ath12k-ahb.yaml | 301 ++++ drivers/net/wireless/ath/ath12k/Kconfig | 6 + drivers/net/wireless/ath/ath12k/Makefile | 1 + drivers/net/wireless/ath/ath12k/ahb.c | 1254 +++++++++++++++++ drivers/net/wireless/ath/ath12k/ahb.h | 80 ++ drivers/net/wireless/ath/ath12k/ce.c | 92 +- drivers/net/wireless/ath/ath12k/ce.h | 16 +- drivers/net/wireless/ath/ath12k/core.c | 35 +- drivers/net/wireless/ath/ath12k/core.h | 12 +- drivers/net/wireless/ath/ath12k/hal.c | 82 +- drivers/net/wireless/ath/ath12k/hal.h | 66 +- drivers/net/wireless/ath/ath12k/hw.c | 477 +++++++ drivers/net/wireless/ath/ath12k/hw.h | 15 + drivers/net/wireless/ath/ath12k/pci.c | 12 +- drivers/net/wireless/ath/ath12k/pci.h | 2 + drivers/net/wireless/ath/ath12k/qmi.c | 169 ++- drivers/net/wireless/ath/ath12k/qmi.h | 1 + 17 files changed, 2520 insertions(+), 101 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/wireless/qcom,ath12k-ahb.yaml create mode 100644 drivers/net/wireless/ath/ath12k/ahb.c create mode 100644 drivers/net/wireless/ath/ath12k/ahb.h base-commit: 400568fb3b022247c1603fdbdd6444b3ef14ffce -- 2.34.1
