WCN6750 is the WLAN chip on Qualcomm Snapdragon SoC SC7280; Though being a PCIe based solution, it is not attached to the APSS processor (Application Processor SubSystem), it is instead attached to another tiny processor called WPSS Q6 processor (Wireless Processor SubSystem) on the SC7280 MSM, where the WLAN firmware runs, and it is the WLAN firmware running on the Q6 processor which enumerates WCN6750, as a result APPS processor would never know such a device being present in the system and would not detect the WCN6750 hardware unless and otherwise WCN6750 is registered as a platform device. This is the reason behind adding WCN6750 WLAN node in the device tree. Add WCN6750 wireless driver support, its based on ath11k driver.
