ath11k: Add support for WCN6750 device

2022-05-02T13:59:08Z

WCN6750 is non-DBS 2x2 11AX chipset. Unlike QCA6390 which is a DBS (dual band simultaneous) solution (2 LMACs), WCN6750 has a single LMAC supporting 2G, 5G and 6G bands but will operate only on one band at any given point. WCN6750 is a PCIe based solution, but it is attached to the WPSS (Wireless Processor SubSystem) Q6 processor, hence it is enumerated by the Q6 processor. It is registered to the APSS processor (Application Processor SubSystem) as a platform device(AHB) and remoteproc APIs are used to boot up or shutdown the device like other AHB devices. Also, Device information like BAR and it's size is not known to the APSS processor as the chip is enumerated by WPSS Q6. These details are fetched over QMI. STA and AP modes are supported. Verified basic connectivity and ping in both the modes. An important point to note is that though WCN6750 is a PCIe device, it cannot be attached to any other platform except on Qualcomm Snapdragon SoCs due to the aforementioned reasons.

ath11k: Refactor PCI code to support WCN6750

2022-04-05T08:05:27Z

Unlike other ATH11K PCIe devices which are enumerated by APSS processor (Application Processor SubSystem), WCN6750 gets enumerated by the WPSS Q6 processor (Wireless Processor SubSystem); In simple terms, though WCN6750 is PCIe device, it is not attached to the APSS processor, APSS will not know of such a device being present in the system and therefore WCN6750 will be registered as a platform device to the kernel core like other supported AHB devices. WCN6750 needs both AHB and PCI APIs for it's operation, it uses AHB APIs for device probe/boot and PCI APIs for device setup and register accesses. Because of this nature, it is referred as a hybrid bus device. Refactor PCI code to support hybrid bus devices like WCN6750.

ath11k: Add basic WoW functionalities

2022-03-18T15:34:37Z

Implement basic WoW functionalities such as magic-packet, disconnect and pattern. The logic is very similar to ath10k. When WoW is configured, ath11k_core_suspend and ath11k_core_resume are skipped as WoW configuration and hif suspend/resume are done in ath11k_wow_op_suspend() and ath11k_wow_op_resume().

ath11k: refactor debugfs code into debugfs.c

2020-09-22T07:41:41Z

If CONFIG_ATH11K_DEBUGFS is disabled there are warnings debug.c: drivers/net/wireless/ath/ath11k/debug.c:36:20: warning: 'htt_bp_lmac_ring' defined but not used [-Wunused-variable] 36 | static const char *htt_bp_lmac_ring[HTT_SW_LMAC_RING_IDX_MAX] = { | ^~~~~~~~~~~~~~~~ drivers/net/wireless/ath/ath11k/debug.c:15:20: warning: 'htt_bp_umac_ring' defined but not used [-Wunused-variable] 15 | static const char *htt_bp_umac_ring[HTT_SW_UMAC_RING_IDX_MAX] = { | ^~~~~~~~~~~~~~~~ Fix this by refactoring debugfs code to debugfs.c. This also reduces the number of ifdefs in debug.c and makes it easier to maintain the code. No functional changes. Compile tested only.

ath11k: register MHI controller device for QCA6390

2020-08-17T10:07:12Z

Modem Host Interface (MHI) is a communication protocol to communicate with external Qualcomm modems and Wi-Fi chipsets over high speed peripheral buses. Even though MHI doesn’t dictate underlying physical layer, protocol and MHI stack is structured for PCI based devices. Register directly with MHI subsystem as a MHI device driver for firmware download to QCA6390.
