Unlike QCA6390/WCN6855 which are DBS (dual band simultaneous) solutions (2 LMACs), WCN6750 has a single LMAC supporting 2G, 5G and 6G bands. It can be operated only on one band at any given point. WCN6750 is a PCIe device. Unlike other supported ATH11K PCIe devices which are directly attached to APSS (Application Processor SubSystem), WCN6750 is not attached to APSS, it is attached to the WPSS (Wireless Processor SubSystem) Q6 processor, the FW which runs on the Q6 processor will enumerate the PCIe device. Since APSS is unaware of such a device, it has to be registered as a platform device(AHB) to the kernel for device probing. Like other AHB devices, remoteproc APIs are used to boot up or shutdown of WCN6750. WCN6750 uses both AHB and PCIe ATH11K APIs for it's operation. It uses AHB APIs for device probe and booting of the remote processor. Once device is booted up, it uses ATH11K PCIe APIs for initialization and register access. Hence, it is referred as hybrid bus device in the rest of this series. Since the chip is enumerated by WPSS Q6, device information like BAR and BAR size is not known to the APSS processor. A new QMI message called device info QMI request will be sent to the target for fetching these details. STA and AP modes are supported; Basic connectivity and ping are verified 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.
