This SSID uniquely identifies the system, which enables the driver to read the correct firmware and tuning for that system from linux-firmware. Currently there is no way of reading this property from device tree. Add an equivalent property in device tree to perform the same role. --- fd9814554328e189216bb1488c17157462600e99
